Yield-increasing fertilizer for corn

Abstract

The invention discloses a yield-increasing fertilizer for corn. The fertilizer consists of the following raw materials in percentage by weight: 8 to 16 percent of plant ash, 10 to 16 percent of nitrogen fertilizer, 18 to 37 percent of soya bean meal, 18 to 25 percent of phosphatic fertilizer, 6 to 10 percent of sand, 4 to 10 percent of calcium superphosphate, 4 to 9 percent of potassium sulphate, 1 to 2 percent of triple superphosphate, 0.5 to 1 percent of yield-increasing agent, 0.5 to 1 percent of chemical fertilizer, 0.5 to 1 percent of derosal and 0.5 to 1 percent of dichlorovos. The fertilizer is prepared by the following steps of: combining the first ten raw materials completely in proportion; putting the mixture into a stirrer to stir for 50 minutes, and taking the stirred mixture out; adding the derosal and the dichlorovos into the stirred mixture, and uniformly stirring the mixture; putting the mixture into the stirrer to stir for 30 minutes, and taking the stirred mixture out; and molding the stirred mixture into a cylindrical fertilizer pile of which the weight is 150 grams, the height is 8 centimeters and the width is 6 centimeters by using a molding machine, wherein the molded fertilizer pile is required to be compact and be difficult to smash when taken by hands.

Description

technical field [0001] The invention relates to a yield-increasing fertilizer, in particular to a corn yield-increasing fertilizer. It belongs to the technical field of planting fertilizers. Background technique [0002] Corn aliases: Baogu, Baolu, corn, dasi, cob, corn, corn, Yuling, corn, dilute wheat, six grains, reed millet, pearl rice, red wheat, barley bag, etc. Poaaceae, an annual cereal plant, originated in North, Central and South America. The plants are tall, with strong, straight stems. The leaves are narrow and large, with wavy edges, alternate on both sides of the stem. Male flowers inflorescence spicate terminal. The spikes of the female flowers are axillary, and become grain spikes after maturity, with a thick central axis, and the spikelets develop into two rows of grains after being arranged in pairs. The ears of corn are covered with multi-layered metamorphic leaves, which are called foreskins. The seeds are edible. Maize belongs to the Poaceae Maize...

Problems solved by technology

[0003] At present, in the process of planting corn, people generally use chemical fertilizers as the main fertilizer and add some urea. Although the effect is very good, the nutrients produced in the chemical fertilizers are far from meeting the nutritional needs of corn, resulting in the growth and development of corn. slow, the soil becomes hard, and the corn produced is small in size, light in weight, low in kilograms, and prone to various diseases and insect pests
