Compound fertilizer for increasing oilseed rape survival rate

Abstract

The invention aims to provide a compound fertilizer capable of increasing the survival rate of oilseed rape so as to solve the problems in the background technology. The compound fertilizer is characterized by including raw materials in parts by weight: 3-10 parts of urea, 20-35 parts of zinc sulfate, 15 to 25 parts of disodium octaborate tetrahydrate; 4-8 parts of manganese sulfate, 2-6 parts ofammonium molybdate, 2-5 parts of ferrous sulfate, 1-3 parts of copper sulfate, 10-16 parts of monopotassium phosphate, 12-15 parts of calcium superphosphate, 10-22 parts of animal waste, 2-8 parts ofborax solution, 15-21 parts of choline chloride, 17-25 parts of wetting agent, 10-16 parts of organic acid and 10-25 parts of wheat flour. The beneficial effects of the invention are that: the fertilizer is reasonable in formula, low in cost, scientific and practical in production process, simple in preparation method and process, suitable for large-scale industrial production, capable of changingadverse conditions such as soil hardening and poor air permeability, lasting in fertilizer efficiency, quick in effect, especially suitable for tuberous root and tuber plants, and capable of effectively improving the yield and quality of the tuberous root and tuber plants.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a compound fertilizer for improving the survival rate of rapeseed. Background technique [0002] The main pests of rapeseed are aphids, leafhoppers, diamondback moth, etc. Rapeseed is very sensitive to nitrogen, phosphorus, potassium, and boron during the entire growth period. When nitrogen is deficient, the leaves turn red and the feet fall off; phosphorus fertilizer is beneficial to root growth and enhances resistance; potassium fertilizer can improve disease resistance, cold resistance, and lodging resistance; boron deficiency will make rapeseed not full, affecting yield and oil yield. [0003] Rapeseed root damage generally occurs at the roots, and the pathogens generally invade from the root hairs or young roots, forming tumors on the main roots or lateral roots. The surface is smooth and white in the early stage, and later the color becomes brown, rough, and cracked. It is eas...

Problems solved by technology

However, the plants are slender, the branches are reduced, and the yield is sharply reduced. This kind of soil-borne disease is often limited by human cultivation conditions, and it is difficult to apply fertilizer multiple times, resulting in crops dying due to lack of fertilizer.
