Compound fertilizer for vegetable planting

Abstract

The invention relates to the field of agricultural fertilizers and particularly relates to a compound fertilizer for vegetable planting. The compound fertilizer is prepared from the following raw materials in parts by weight: 30-45 parts of cottonseed hull powder, 10-20 parts of coconut shell powder, 10-20 parts of walnut shell powder, 5-15 parts of urea, 4-5 parts of potassium chloride, 20-30 parts of humic fertilizer, 10-15 parts of urea formaldehyde, 2-7 parts of manganese sulfate, 5-8 parts of phosphorus pentoxide, 4-9 parts of starch ether and 10-14 parts of coal gangue powder. The fertilizer provided by the invention has a slow release effect, is capable of keeping long-lasting fertilizer effect of the fertilizer and is capable of increasing the use ratio; according to the compound fertilizer, the soil cannot be hardened, the moisture and fertilizer retention properties of the soil are increased, the nutrition components can be increased and the toxic matters are removed, so thatthe compound fertilizer is safe to use; the fertilizer has a synergetic effect for promoting the nutrition absorption of the plants and is capable of promoting the vegetable quality.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a compound fertilizer for vegetable planting. Background technique [0002] my country is a big agricultural country, and it is also a big country in the production and use of chemical fertilizers. At present, my country's total production and application of chemical fertilizers rank first in the world. The status of fertilizers in agricultural planting and production is very important, especially chemical fertilizers, which play a pivotal role in increasing agricultural production, and the input of chemical fertilizers is increasing year by year.

[0003] In vegetable planting and production, due to some unreasonable factors in the use of fertilizers, the application of organic fertilizers and micro-fertilizers is ignored, the ratio of organic fertilizers to inorganic fertilizers is seriously unbalanced, unreasonable fertilization and improper fertilization methods lead to low fertilizer utilization rates, resulting in Vegetable nutritional imbalance, lodging, yield reduction, and quality decline, while the soil properties of cultivated land deteriorated, seriously polluting the environment
