Problems solved by technology

The biggest obstacle to dry farming is the ineffective evaporation of soil moisture. The conventional semi-film flat ground coverage rate before sowing is low, generally only 50% to 60%. From April to June) the soil moisture is extremely poor, which often leads to the inability to sow spring crops such as corn

Embodiment Construction

[0035] A full-film double-furrow sowing method, comprising the following steps:

[0036] (1) Select plots with flat terrain, soil thickness of more than 1 meter, soil particles less than 0.002mm, clay content of more than 15%, organic matter content of 1-5%, and slope of less than 15 degrees.

[0037] (2) After harvesting the previous crops in autumn, plow 25-30 cm deep to remove the stubble, and harrow until the ground is level.

[0038] (3) Spread farmyard manure evenly on the surface at 3000-5000kg / mu before ridge formation, and at the same time apply 25-30kg of urea per mu, 50-70kg of superphosphate, 15-20kg of potassium sulfate, 2-3kg of zinc sulfate or Special fertilizer for corn (provided by Xinyi Xingang Chemical Fertilizer Co., Ltd.) 80kg.

[0039] (4) Row and ridge: start from 35 centimeters away from the edge of the ground and divide the entire field in the order of one small ridge and one large ridge, and open trenches and ridges according to the planting directio...

Abstract

The invention relates to a full film double-furrow seeding method, comprising the following steps: (1) selecting a plot; (2) deep-ploughing and ploughing stubble after preceding crops are harvested in summer and autumn, and raking until the ground is even; (3) evenly spraying fertilizer on the ground surface according to 3000-5000kg / acre before ridging; (4) rowing and ridging; (5) disinfecting soil; (6) laminating in autumn or laminating with ice; (7) selecting seeds; (8) at the middle and the end of April, carrying out bunch planting sowing when temperature keeps stable and exceeds 10 DEG C; (9) carrying out field management in a seedling stage, a middle stage and a rear stage, and preventing and curing insect pests; and (10) cultivating and recovering a residual film. The method is simple and feasible and can effectively solve the problem of invalid evaporation of soil moisture in a dry farming agricultural region.

Description

technical field [0001] The invention relates to a sowing method, in particular to a full-film double-furrow sowing method. Background technique [0002] Gansu Province is located in the northwest inland, with serious shortage of water resources and permanent seasonal drought. It is a typical arid and semi-arid agricultural province in western my country. Its extremely fragile ecological environment and harsh natural conditions lead to fluctuations in agricultural production. Low and unstable. The biggest obstacle to dry farming is the ineffective evaporation of soil moisture. The conventional semi-film flat ground coverage rate before sowing is low, generally only 50% to 60%. From April to June) the soil moisture is extremely poor, which often leads to the inability to sow spring crops such as corn. Therefore, there is an urgent need for a seeding method that can solve the ineffective evaporation of soil moisture in dry farming areas. Contents of the invention [0003] T...
