Embodiment 1

[0040] Choose high-quality, high-yield new sweet waxy corn varieties according to the local soil and weather conditions. Dry the seeds for 2 days 4 days before sowing, and dress the seeds after the drying, mixing and dressing the seeds at a ratio of 2500 parts of seeds and 10-15 parts of 15% Fenmeining wet powder. Before sowing the seeds, deep plow and fertilize the planting land, the fertilization is every 667m 2 Apply 4000kg of decomposed farmyard manure and 30kg of compound fertilizer of nitrogen, phosphorus and potassium as base fertilizer. Then, the planting method was adopted for planting in the shape of a font, the specific planting row spacing was 50cm, and the planting spacing was 22cm. Plant 2 seeds in each hole. After the seeds are sowed, a deficient nest with a depth of 5 cm is set above the planting ground where the seeds are planted. The deficient nest is semicircular, and then the surface of the deficient nest is covered with plastic film. The soil temperature...

Embodiment 2

[0046] Choose high-quality, high-yield new sweet waxy corn varieties according to the local soil and weather conditions. Dry the seeds for 1 day 5 days before sowing, and dress the seeds after the drying, and mix and dress the seeds with 5-7 parts of 50% carbendazim wettable powder and 1000 parts of seeds. Before sowing the seeds, deep plow and fertilize the planting land, the fertilization is every 667m 2 Apply 4,500 kg of decomposed farm manure and 35 kg of compound fertilizer of nitrogen, phosphorus and potassium as base fertilizer. Afterwards, the planting method was used for planting in the shape of a font, the specific planting row spacing was 55cm, and the planting plant spacing was 23cm. Plant 3 seeds in each hole. After the seeds are sowed, a deficient nest with a depth of 6 cm is set above the planting ground where the seeds are planted. The deficient nest is semi-elliptical, and then the surface of the deficient nest is covered with plastic film. The soil temperat...

Embodiment 3

[0048] Choose high-quality, high-yield new sweet waxy corn varieties according to the local soil and weather conditions. Airing the seeds for 1 day 4 days before sowing, and dressing the seeds after drying, mixing the seeds with 3,500 parts of phoxim solution and 20,000 parts of seeds, and simmering for 4 hours. Before sowing the seeds, deep plow and fertilize the planting land, the fertilization is every 667m 2 Apply 5000kg of decomposed farmyard manure and 40kg of NPK compound fertilizer as base fertilizer on the planting land. Then, the planting method was adopted for planting in the shape of a product, the specific planting row spacing was 60cm, and the planting plant spacing was 25cm. Plant 2 seeds in each hole. After the seeds are sowed, a deficient nest with a depth of 7 cm is set above the planting ground where the seeds are planted. The deficient nest is semicircular, and then the surface of the deficient nest is covered with plastic film. The soil temperature in th...

Abstract

The invention relates to the field of agricultural planting, and provides an early maturing culture method of corn. The method comprises the steps that seeds are sowed in a planting field, and a hole is arranged above the sowed seeds. The hole is covered with a mulching film. After seeds sprout, holes are punched in the surface of the mulching film, and seedlings can pass through the film holes to keep growing. The method can make fresh edible corn on the market around 10 days earlier, which effectively increases farmers' income and ensures green safety production. The method is capable of making effects of cold protection, seedling protection and soil moisture conservation, and has the advantages of low cost, advance, practicality and strong operability, thereby facilitating the technical extension and radiation and playing a role of driving effect.

Description

Technical field [0001] The invention relates to the field of agricultural planting, in particular to a corn early maturity cultivation method. Background technique [0002] In view of the current income of normal planting of fresh corn at about 3,500 yuan per mu, and early planting of up to about 5,000 yuan per mu, early market can produce higher economic benefits. However, the spring temperature in the Hexi Corridor is low, and open field sowing is caused by late frost. It is prone to freeze seedlings. However, the use of steel frame greenhouses for planting occupies too much area and the cost increases too much. Summary of the invention [0003] The present invention provides an early-maturing corn cultivation method, which aims to solve the problem of frozen seedlings caused by low late frost temperature in open field planting of fresh corn, which can effectively prevent cold and protect seedlings, and at the same time effectively reduce the cost. [0004] The present invention...
