Abstract

The invention discloses compound fertilizer for corn insect pests. The compound fertilizer is prepared from potassium oxide, calcium carbonate, ammonium nitrate, diammonium phosphate and magnesium nitrate. The fertilizer prepared by the invention contains the potassium oxide, the calcium carbonate, ammonium nitrate, diammonium phosphate and magnesium nitrate. The acidity of soil is effectively improved, insect pests are prevented from occurring and the growth and yield increasing of corns are facilitated.

Description

technical field [0001] The invention relates to the field of corn planting, in particular to a compound fertilizer for corn pests. Background technique [0002] Corn is a temperature-loving crop and requires higher temperatures throughout the growth period. The biologically effective temperature of corn is 10°C. Seed germination requires 6-10°C, slow germination below 10°C, vigorous germination at 16-21°C, optimum germination temperature of 28-35°C, and stop germination above 40°C. The seedling stage can withstand short-term temperature of -2---3℃. The jointing stage requires 15-27°C, the flowering stage requires 25-26°C, and the filling stage requires 20-24°C. Different corn varieties have different temperature requirements, and the early-maturing varieties in my country require accumulated temperature [0003] 2000--2200℃; middle-maturing varieties 2300-2600℃; late-maturing varieties and 25OO--28OO(3000)℃. Most of the world's corn production areas are concentrated in ...
