Required to supply plant nutrients in the soil

 Flower fertilization to the general principle is based on the biological characteristics of different types and growth stages, in the type of fertilizer, materials, and facilities into the time and method to achieve both reasonable. Basal fertilizer was applied, Flowers and Plants in soil preparation before planting in conjunction with, potted flowers in the pots when; top dressing was applied, and generally Bo fat Dorsch principle. Flower seedlings in the period, more potassium fertilizer should be applied; growth period, more nitrogen fertilizer should be applied; flowering and seed, more fertilizer should be applied phosphorus. Facilities into the dressing should choose sunny, and dry soil is better than that. Flowers need fertilizer, but leaves them visible to judge. Where the dark green leaves, thick and wrinkled by the quality as too fat, should stop facilities; leaves were yellow and thin-walled, as Quefei advised to make fertilizer. How to root outside the dressing

also known as A fertilization method. Trace elements with chemical fertilizers or spraying a very dilute solution of the leaves in the flower, so fertilizer solution is absorbed through the leaves and use. Plant roots absorb nutrients can supplement the deficiency. Spraying time for the early morning, evening or cloudy day is appropriate, the sun and heavy wind are not large, the main class for the flowers and rare flowers, many flowers growing in the busy period or when the lack of an element.

What is the usefulness of top-dressing

crop growth period in the nutritional needs for fertilizer application. Flowers generally available with inorganic fertilizer-based fertilizers, and when the supply of plant growth and development. Applied fertilizer, the fertilizer shall proportion watered by watering it later, but the flowers and foliage to prevent direct contamination

the basic principles of fertilization is timely and appropriate manner, a few times, Qin Shi, Shi thin. Especially the powdered chemical fertilizer, diluted with water to moderate multiples to avoid fertilizer injury; fertilizer release position as far away from the roots of some plants to avoid root contact, no harm to the roots; outdoor plant nutrient demand, intensity of photosynthesis , to be more than the amount of fat, while a small amount of shade plants enough fertilizer; plants grow fast, and strong growth potential to be fat volume, growth potential weak low fertilizer requirement, in accordance with the provisions of concentration and precise preparation.

Fertilization: Fertilization and Foliar Fertilizers generally two kinds of sub-roots. Fertilizer applicator divided into roots, fertilizing, bar facilities and environmental facilities. Applicator is about evenly spreading fertilizer on the soil surface of cultivated area, the application of convenience, but the loss of fertilizer is easy, using low; fertilizing the plants near the digging, after the fertilizer applied into the casing, this law applies to fertilizer to be more or focus more on plants; ring applied for green trees along the drip line of about 30 cm deep excavation ditch, covering soil after application. Foliar fertilizer, the fertilizer deep in water, non-toxic and will not burn leaves. Foliar fertilizer advantages are: rapidly absorbed to replenish nutrients; can increase photosynthetic rate, increase breathing efficiency and leaf enzyme activity; to avoid the fixed nutrient, high utilization, saving fertilizer; from matrix environment, substrate constraints; timely corrective element deficiency symptom bogey six urea

ammonium bicarbonate mixed with a bogey. Urea applied to soil, the ammonia can be converted into absorbed by crops, the conversion rate in alkaline conditions than under acidic conditions is much slower. Ammonium bicarbonate alkaline soil fertilized response, ph value of 8.2 ~ 8.4. Farmland mixed fertilizer ammonium bicarbonate and urea, ammonia into urea will greatly slow down the speed, likely to cause the loss of urea and volatile loss. Thus, urea and ammonium bicarbonate application should not be mixed or both.

two bogey ground applicator. Urea applicator on the surface, room temperature 4 to 5 days to go through the conversion process to be absorbed by crops, most of the ammonium nitrogen in the process of being evaporated, only about 30% utilization rate, if the alkaline soil and organic matter content soil applicator, faster and more loss of nitrogen. Therefore, nitrogen is not the surface applicator.

bogey for the three types of fertilizer. Urea in the production process, often produce a small amount of biuret. Biuret content of more than 2%, it will produce toxic seed and seedling. Urea into the seeds and seedlings, the cause of protein denaturation, seed germination and seedling growth.

four bogey immediately after the irrigation facilities. Urea, ammonia nitrogen fertilizer, applied later can be converted into ammonia nitrogen absorption by crops. Transformation process due to soil, water and temperature conditions are different, the time be long or short, generally after 2 to 10 days to complete, if applied immediately after urea irrigation drainage or dry in the rain before the application of urea will dissolve in water loss .

Five Note mixed with the alkaline fertilizer applied. After the urea applied in order to be converted into ammonia nitrogen use by crops. Ammonia under alkaline conditions, most of the nitrogen into ammonia will evaporate, so the urea can not and lime, plant ash, calcium magnesium phosphate fertilizer and other basic application of mixed fertilizer or both.

bogey six facilities in the celery. Required during the whole growth of celery a lot of nitrogen topdressing fertilizer, but not urea. As topdressing urea, celery, more thicker fiber, plant aging, slow growth, and food with a bitter taste of poor quality. Celery suitable facilities ammonium bicarbonate, ammonia and organic fertilizers, beneficial to improve quality.

how to use human waste

human waste into a more complete fertilizer containing nitrogen, which accounted for 0.5% -0.8% nitrogen, phosphate 0.2% -0.4% 0.2% -0.3% with potassium hydroxide, in addition to containing calcium, iron, sulfur and other trace elements and organic matter. Human waste to be stored by a half months or so before use, for seedlings, or when the water is 5-10 times more light for the seedlings when large water 2-4 times, people break down more easily after the soil was quickly absorbed and used flowers. Shade to be sealed in storage to prevent loss of volatile organic nitrogen. Avoid with plant ash, lime and other alkaline fertilizer mix. Human waste can be used for basal and top dressing fertilizer is usually effective for good. Shall be applied seedlings were growing stocking weight of decision watered, the general amount of seedlings: 20% of feces or urine, dilute water 80%; large amount of seedlings: feces or urine -50%, 30%, 70% Duishui - 50%. The concentration of too much, easy to burn seedlings. Multi-use for garden and farm, the family should not be.

What is the usefulness of mixed fish

for the scales, guts and other fish waste. Nitrogen, phosphorus component is greater, and after full maturity heap steep, the more basal or top dressing as a flower of use. In order to avoid dissemination of the heap when retting rancid and attract maggots of flies lay their eggs, ash or other covering to cover. The type of compound fertilizer and rational application

before appearing on the market many types of fertilizer, mainly based on crop nitrogen, phosphorus and potassium needs of different mixed ratio increases. There citrus specific compound, Shantou food specific compound, specific compound of cotton, rice specific compound, specific compound sugar cane juice, vegetable special fertilizer, lawn fertilizer, and so class-specific.

compound can be divided into 10 categories. The first is inorganic compound. That inorganic chemical fertilizers made by physical or chemical methods of nitrogen, phosphorus, potassium, or of which 2 Nutrition fertilizer. The second type is an inorganic compound organic. The inorganic compound fertilizers such as the addition of a large number of organic cake, bone meal, animal waste, peat and other products made. The third category is compound fertilizer with trace elements. Recently many manufacturers packaging is marked with zinc and other trace elements boron. The fourth category is with rare earth fertilizer. That with a certain rare earth fertilizer, such as rare earth ammonium bicarbonate. The fifth type is sprayed with fertilizer. Powder and liquid into 2 major categories, with a certain amount of nitrogen, phosphorus, potassium and trace elements, which require a higher water-soluble, insoluble requirements below 5%. VI is a liquid fertilizer. More of such products in the United States and Europe, mainly with liquid fertilizer, or irrigation system root fertilization. VII is a compound fertilizer containing micro-organisms, mainly refers to the inorganic compound in the organic compound added a variety of species. VIII is a compound fertilizer with pesticide. That contain a certain amount of fertilizer pesticides, mainly herbicides containing pesticides. Class IX humic acid compound fertilizer is. Humic acid on the growth of plant roots have a certain stimulus, but because of its more expensive, the added humic acid compound fertilizer manufacturers are not many. First class is the other fertilizer BU. Such as magnetic fertilizer, mainly refers to the compound through a special magnetic material magnetic devices, and greatly reduced the total nutrient content, the fertilizer is currently difficult to determine.

fertilizer nutrient because of its complete content, can increase crop yield and quality, more and more users. Should grasp the following points in the application:

one suitable as base fertilizer. Crop uptake of P and K in the critical early period of general, while phosphorus and potassium in the soil mobility of a small, good fertilizer as base fertilizer. Statistics study showed that crop growth period for recovery with a single mass on nitrogen case of Pakistan, most crops at the time of application of fertilizer: Department for basal

is better; if growth period does not meet the elemental nitrogen fertilizer as top dressing, while 75% of the fertilizer as basal fertilizer, and the other 25% of the nitrogen, or basal, top dressing better half and half.
