Notes On Application Technology Of Bio-organic Fertilizer
: appropriate moisture content, temperature, optimize the application method.
1. Appropriate moisture content
No matter which fertilization method is adopted, it should be applied under the appropriate moisture content, so that the fertilizer can be rapidly decomposed, diffused and permeated, and be absorbed and transformed by crops as soon as possible.
2. Appropriate temperature.
Fertilization time should be determined according to the characteristics of different crops and the length of growth period. The growth period of cotton is long, which can be used as base fertilizer or as heading fertilizer in bud. Fruit trees are generally recommended for use from December to January of the following year. The temperature below 5 ℃ or above 35 ℃ should not be commonly use, with 10 ℃ to 25 ℃ when applying the best effect.
3. Optimize the application method.
Biological organic fertilizer should be applied as early as possible, the amount of each acre of application is not less than 40 kg, with the effect of rapid fertilizer with better application.
Microbial fertilizer is also responsible for the transformation of soil organic matter to humus, increasing the soil aggregate structure, improving the capacity of water and fertilizer retention, activating solidified nutrients of soil, and improving the utilization rate of fertilizer. At the same time, beneficial microorganisms in microbial fertilizers secrete various beneficial substances to the soil, such as growth stimulating hormone, indoleacetic acid, gibberellin and various enzymes, thus effectively promoting nutrient conversion, reducing the occurrence of soil-borne diseases and repairing the contaminated soil. Therefore, microbial fertilizer can be said to be the ideal fertilizer for green agriculture and organic agriculture, and has a broad prospect in the sustainable development of agriculture.
