To make organic fertilizer at home, the following three methods can be used, which are simple and practical to meet the needs of vegetable growth.
1. Use kitchen waste to make fertilizer
Collect rotten fruits and rotten vegetable leaves, put them in a sealed bucket, fill them with water, add three parts of brown sugar or microbial bacteria, and close the lid to seal. In about two or three months, it will be completely ripe. Fermented fertilizer can be applied with water, which plays a role in fertilizer replenishment, insect prevention and disease prevention.
Fertilizers fermented with rotten fruits and vegetables contain more nitrogen. In order to supplement phosphorus and potassium elements, in the fermentation vat can add animal offal, rice water, egg shells, etc., after decomposition, is a more nutrient-rich organic fertilizer, used in melons, fruits and vegetables, can improve quality.
2. Make cake fertilizer by using soybeans, rapeseed, peanuts and other residues
Cake fertilizer is a kind of high-quality organic fertilizer, if the residue is crushed directly into the soil, the utilization rate of nutrients is very low, must be fermented and then used, so that organic nitrogen and phosphorus, conversion of inorganic state, improve the utilization rate of fertilizer.
Soybeans, rapeseed, peanuts and other oil-pressed residues are first steamed and then cooked with starter culture. Cake fertilizer contains more nitrogen and phosphorus, when used, it should be used with potassium fertilizer.
These raw materials can also be made into fertilizer water, using cake fertilizer or tofu residue 1 to 2 pounds, plus 5 pounds of water, put into a plastic bucket, sealed and decomposed for more than 6 months. During the fermentation process, the cake fertilizer has a large taste and should be placed in a ventilated place. Fermented fertilizer water should be added to the appropriate amount of water, which should be used as topdressing.
3, the use of chicken manure, cow manure, sheep manure and other production of organic fertilizer
Collect the animal manure, dry it and put it in a plastic bag, and then add water, the amount of water does not need to be too much, you can drown the manure on the line, seal the mouth of the bag, and rot it. During the fermentation process, gas will be generated, so it should not be overfilled, and space should be left.
When manure is used as a base fertilizer, it can also be made of high-temperature stacking, which takes a long time and occupies a large area. The feces that need to be decomposed are added to the straw, straw, and a small amount of urea, calcium superphosphate, etc. are piled up. Add an appropriate amount of water, cover with plastic film and ferment. In order to decompose fully and speed up the decomposition, you can add a humectant.
There are three ways to grow organic fertilizer at home, and farmers can choose according to raw materials. When using homemade organic fertilizer, farmers should pay attention to several aspects: First, organic fertilizer must be fully decomposed before use, if it is found that there is a situation of burning roots or fertilizer damage, it is necessary to water in time, flush the appropriate amount of rooting agent, and alleviate the fertilizer damage. Second, when organic fertilizer is used, it should be used in combination with chemical fertilizers, and the nutrients are comprehensive, which is conducive to vegetable growth.
