Abstract

The invention relates to the technical field of agricultural fertilizers, and concretely relates to a special fertilizer for corn. The fertilizer comprises, by weight, 200-300 parts of urea, 100-160 parts of monoammonium phosphate, 100-140 parts of potassium sulfate, 10-20 parts of a special filler and 30-50 parts of a mixed microelement fertilizer. The special fertilizer is only applied once before corn transplantation in the whole corn growth process, has long fertilizer efficiency lasting time, has a long-acting slow release effect, and avoids damages of multi-time fertilization to the plants and roots of corn. The special fertilizer has scientific and reasonable ratio, allows the corn to have the characteristics of good growth vigor, lodging resistance and few insect diseases, and realizes no nutrient deficiency symptom in the whole growth process. The N / P / K ratio of the special fertilizer avoids harms brought by continuous cropping, and makes the crops grow fast and have high output.

Description

[0001] technical field [0002] The invention relates to the technical field of agricultural fertilizers, in particular to a special fertilizer for corn. Background technique [0003] Corn is an annual herb plant with tall plant shape, wide and long leaves, monoecious flowers, male inflorescences grow on the top of the plant, and female inflorescences grow in the middle and upper leaf axils. It is a cross-pollinated annual crop. There are common names such as corn, stick, corn and pearl rice. Maize is grown on all continents of the world and has become an important feed crop. Corn is the most important raw material for making compound feed, generally accounting for 80%, and the remaining 20% ​​is high-protein additives such as soybean meal or fish meal. [0004] Among the cereal crops in the world, the planting area and total output of corn ranks third after wheat and rice, and the average yield per unit area ranks first. Corn is a warm and short-day crop. From seed g...
