Tea bran retting can water fruit trees. Peanut bran is a high-quality organic fertilizer processed by the by-product of peanut kernel oil extraction. It has a small carbon-nitrogen ratio and decomposes quickly after being applied to the soil. Fertilizer is effective quickly. Because it is rich in phosphorus and potassium, it is generally applied to fruit trees.

1. Put peanut bran powder into water and let it decompose in an oxygen-deficient environment. Ready for use after 2-12 months. The longer the time, the higher the degree of ripe rot and the less likely it is to burn the plants. The ratio of peanut bran to water is about 1:15. When using it, the liquid fertilizer needs to be diluted with water first. The ratio of liquid fertilizer to water is about 1:7. After application, it is best to sprinkle water to avoid burning the plants.

2. First mash the cake fertilizer, then pile it with compost or manure for 2 to 3 weeks, or add decomposed human and animal excrement to the cake fertilizer and let it soak together for 2 -3 weeks is enough. The compost pile is covered with agricultural film to seal it for fermentation to prevent it from attracting flies after it becomes smelly. Cake fertilizer can be used as base fertilizer and top dressing.

① If used as base fertilizer, it should be applied into the soil 7 to 10 days before sowing. In dry land, it can be applied in strips or holes. After application, it should be mixed with the soil. Do not get close to the seeds to avoid affecting seed germination.

② If it is used as top dressing, it must be fermented and decomposed. Otherwise, if it is applied to the soil and continued to ferment, it will generate high heat and easily burn the roots of the crops. Application in paddy fields must be drained first and then spread evenly. Combined with the first tillage, the cake fertilizer and soil are fully mixed. After 2 to 3 days, shallow water is poured again. In dry land, hole application or strip application should be used.

③The application amount of cake fertilizer should be determined according to the soil fertility and crop varieties. Low soil fertility and fertilizer-tolerant varieties should be applied more appropriately; otherwise, the application amount should be appropriately reduced. Generally speaking, for medium-fertility soil, the dosage of rice is 30 to 40 kilograms per mu; corn is 35 to 45 kilograms per mu; sugarcane is 60 to 70 kilograms per mu. Since cake fertilizer is a slow-acting fertilizer, attention should be paid to the appropriate amount of quick-acting nitrogen, phosphorus, and potassium fertilizers. For vegetables, due to the short growth period, the application should be reduced according to the specific vegetable growth period and fertilizer tolerance.
