Embodiment 1

[0012] A method for preventing and treating rough dwarf disease of corn by staggering the sowing time of corn, selecting new spring corn variety Danyu 86, applying 3200kg of chicken manure, 16kg of urea, 10kg of potassium chloride, 27kg of superphosphate, and 13kg of urea slow-release fertilizer per mu of land; Use subsoiling full-layer fertilization precision seeding machine, subsoil 30 cm, break the bottom of the plow, increase soil water storage capacity, and reduce water and fertilizer loss; the sowing period is between April 15th and 20th, and mulching with plastic film is better than not mulching The corn sowing period is increased by 15-18 days, and the corn is planted closely in double-planted nests with wide and narrow rows, the row spacing of wide rows is 2.6-2.8 feet, the row spacing of narrow rows is 1.3-1.4 feet, and the spacing of plants is 1.2-1.4 feet; 4500-5000 plants are planted per mu. 80-90 cm wide and 0.008 mm thick black micro-membrane covering, rupture th...

Embodiment 2

[0015] A method for preventing and treating rough dwarf disease of corn by staggering the sowing time of corn. The summer corn Zhengdan 958 is selected, and the open space or courtyard dam with flat terrain, leeward to the sun, good drainage, and easy management is selected as the seedbed. 10-15 days before sowing, the per mu Use 400 kg of fertile and loose loam soil, 250 kg of high-quality human and animal manure, 5-10 kg of superphosphate, and 10 kg of plant ash in the field. Mix them evenly for retting. Add appropriate amount of water to the prepared nutrient soil to adjust the dryness. It is advisable to form a ball and disperse on the ground, and use a fat ball shaper to make a cylindrical fat ball. The size of the fat ball is preferably the size of a duck egg; 3 / 4 of the nutritious soil, put the seeds into the sowing hole of the fertilizer ball, sow only one seed per fertilizer ball, after sowing, cover the fertilizer ball with 1-2cm thick fine soil, then pour water to mo...

Abstract

The invention discloses a method for controlling rough dwarf disease in maize by staggering the maize seeding time. The method includes the steps of subjecting spring maize to mulching and seeding 15-18 days earlier; subjecting summer maize to soft-tray seedling transplanting, and delaying transplanting in fields by 20 days. By the use of the method, damage of maize by pests and diseases can be reduced greatly, and yield and income are increased. The method is simple and easy, the effect of the rough dwarf disease on maize is minimized, economic benefit in planting maize is increased for farmers, and positivity in planting maize is protected for farmers.

Description

technical field [0001] The invention relates to a method for preventing and treating rough dwarf disease of corn by staggering the sowing time of corn, and belongs to the technical field of corn cultivation. Background technique [0002] Corn rough dwarf disease is commonly known as "evergreen corn" and "ginger corn". It can occur from the seedling stage of corn to the tasseling stage, but it is most likely to occur at the seedling stage. The main feature of maize after rough dwarf disease is that white, yellow or dark brown waxy protrusions are produced on the back of heart leaf, leaf sheath and bract. The earlier the onset, the heavier the damage. The seedlings are damaged, the leaves of the diseased plants are dark green, the roots are few, the plants are dwarfed, generally no earing, the tassels are severely degraded, there are no fruit ears or the fruit ears are extremely small, and they are not fruitful. In the adult stage, the internodes in the middle and upper part...
