The organic fertilizer should be fully decomposed and then applied with some animal manure such as pig cow manure and human excrement and directly applied to the soil without fermenting and decomposing. These unfertilized organic fertilizers are decomposed and fermented by microorganisms in the soil, and the ammonia produced is easy to cause crops. Rooting, poisoning, and some will also breed weeds and spread pests and diseases. Therefore, it should be fully fermented and applied, and promote the method of septic tank fermentation in the land side, or wet the compost pile and water, and seal it with soil to make the temperature reach 35 °C ~ 40 °C, after 25-30 The fermentation can be completed in days, and the high-temperature method can fully ferment the manure at 60 ° C, which can kill the eggs and weed seeds in it, and it is safer and more effective when applied.
It is not suitable to concentrate or apply too much, especially when applying fertilizer in dry land. If organic fertilizer is applied directly to the line or near the root of the crop, the water holding capacity of the dry soil is small, the concentration around the root is too large, and the roots are exposed to the fertilizer. The crop is physiologically dehydrated and forms a phenomenon of reverse osmosis, which causes the crop to grow poorly or appears to be wilting and loses water and dead seedlings. Therefore, the organic fertilizer should be uniformly mixed in the soil to be integrated with the soil. In the application of organic fertilizer in the growing season, it should be applied by ditching or hole application, and the soil should be covered after application, and should not be scattered on the ground.
It is not easy to dry and apply some farmers to use organic fertilizers such as pig pens and manure, dried in the sun, or applied to the topsoil of dry crops. As a result, the manure will be exposed to long-term sun and rain, which will cause nitrogen to volatilize. Losses, quick-acting phosphorus and potassium will also be largely lost, and pollution of the environment should be carried out in a pile of decomposing ways.
Rational application of straw, pig manure manure, green manure and other organic fertilizers, the cellulose (ie carbon) content, nitrogen content is small, if the amount of this fertilizer is too large, it is easy to cause crops in the early stage of nitrogen deficiency and dead seedlings This is why rice straw stalks must be mixed with ammonium bicarbonate to supplement nitrogen. Therefore, the application of organic fertilizers in crops is not as good as possible. Generally, 1000-1500 kg of fertilizer per mu or 1000-1500 kg of green manure is applied, and an appropriate amount of ammonium bicarbonate or urea is added at the time of application to adjust the carbon-nitrogen ratio to meet the microbial Need to prevent the occurrence of microbial and crop nitrogen.

Royal Jelly is also called Bee Milk. The fresh royal jelly is slightly ropy milk paste substance; it is the excretive mixture of nutrition gland and maxilla gland of the head of little worker bee. The worker bees use this to feed the 1-3 days` worker bee larva and drone larva, 1-5.5 days` queen bee larva and queen bee in the oviposition period. The royal jelly is the biologic product containing very complicated active elements which contains almost all the nutrition elements required by the growth of the human body.
