Embodiment 1

[0013] Soil preparation and furrowing: On the basis of land preparation and leveling, mechanical furrowing is made. The width of the furrow surface is 110cm, and the width of the furrow stem is 30cm. A sowing belt is sown on both sides of the 2.5cm away from the furrow stem. A sowing belt is composed of two rows of seeds. The distance between two rows of seeds is 15cm, and the two rows of seeds are staggered. The vertical distance between the seeds in two adjacent holes is the planned plant spacing

[0014] Maize seedling raising: choose sandy loam soil with good soil fertility and decomposed organic fertilizer in a ratio of 5:2, mix well, sterilize with chlorothalonazol, put it into 128 or 72 hole trays after standing for 10 days; pour the prepared plug trays Water on the soles of the feet, live broadcast 1 grain / hole of dry seeds, cover with 1-1.5cm thick fine soil, and then cover with a layer of film or sunshade net; when the seedlings have emerged, control the temperature a...

Abstract

The invention discloses a corn high-yield and lodging-resistant cultivation method which includes the following steps that on the basis of soil preparation and land formation, a rectangular piece of land is mechanically made, the width of the face of the rectangular piece of land is 110 cm, the width of a ridge of the rectangular piece of land is 30 cm, seeding strips are seeded on the positions, away from the two sides of the ridge of the rectangular piece of land by 2.5 cm, each seeding strip is composed of two rows of seeds, the distance of the two rows of seeds is 15 cm, the two rows of seeds are distributed in a staggered mode, and the vertical distance of every two adjacent holes of seeds is a planned planting distance; corn seedling cultivation is performed, a seedling is grown with three leaves and one core, when a newly-grown root system of the bottom of the corn seedling penetrates out of a water leakage hole in the bottom of a hole plate again by 0.5-2 cm, and the seedling is transplanted into a field; in the early stage of jointing of corns, composite modifiers of 30 kilograms are evenly sprayed on corn plant leaves by utilizing a conventional sprayer, moisture serves as the degree, and the composite modifier of each kilogram comprises 301-400 mg / kg of succinic acid, 0.000031-0.00005 mg / kg of CPPU, 20-60 mg / kg of uniconazole and 50000-100000 mg / kg of monopotassium phosphate.

Description

technical field [0001] The invention relates to a cultivation method, in particular to a high-yield and lodging-resistant cultivation method for corn. 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 co...
