Embodiment Construction

[0052]A specific embodiment of the present invention will be described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0053] A kind of corn lodging resistance high-yield cultivation method provided by the embodiment of the present invention, its specific method is as follows:

[0054] 1. Plow the land and apply enough basal fertilizer: the plowing depth should reach more than 25cm, and the plowing depth is required to be consistent and the ridges should be turned evenly; combined with plowing, 40% to 50% of all organic fertilizers, nitrogen fertilizers and 70% to 80% of phosphate fertilizers should be used. % as basal fertilizer for full-layer deep application; before site preparation, use 50% acetochlor 100-150g or 90% acetochlor 80-100g, mix with water 30-40kg, evenly spray the soil surface to seal the weeds, and then rake land preparation.

[0055] 2. Seed preparation: use commerc...

Abstract

The invention discloses a cultivation method for lodging-resistant and high-yield corn. The method comprises the specific steps of soil ploughing, application of base fertilizer, soil sealing and soilpreparation before sowing, fine selection of seeds, sowing at the proper temperature, regular leaf and seedling management, topdressing of hole applied fertilizer at the right time, reasonable irrigation, prevention and treatment of insect pests and diseases and prevention and removal of weeds. According to the cultivation method for the lodging-resistant and high-yield corn, corn plants plantedby the method are developed in root system, and the activity of the root systems is enhanced; corn stems are short, strong and tough, corn lodging is greatly reduced, and the effect of preventing cornlodging is obvious; the color of corn leaves is deepened, photosynthesis of the leaves is enhanced, and the corn yield is greatly increased.

Description

technical field [0001] The invention relates to a corn cultivation method, in particular to a corn lodging resistance and high-yield cultivation method. Background technique [0002] Corn is an important food and fodder crop in my country, and occupies an extremely important position in the national economy. The abundance or decline of corn production has gradually become an important factor affecting the balance of food supply and demand in my country and determining the development of animal husbandry. Maize lodging is the phenomenon that the stalk changes from an upright state to an inverted one due to external factors. Lodging has always been an important factor affecting the yield and quality of corn. According to relevant statistics, lodging leads to a 15-25% reduction in corn yield. The yield loss of corn due to lodging in my country is nearly 1 million tons every year. At present, with the continuous improvement of the cultivation level of maize in my country, the ...
