Abstract
The invention relates to a method for sowing cotton by warm water drop irrigation. Cottonseeds are sowed at the ditch bottom; drop irrigation belts are paved inside the ditch bottom which is adjacent with the cottonseeds. The drop irrigation is carried out by the warm water so as to satisfy the requirements of water and heat in the soil required by cottonseed germination, thereby replacing plastic films to cover seedlings and overcoming the problem of residual film cumulation inside plow layers.
Description
Technical field
The present invention relates to the method for a kind of drip irrigation with warm water kind cotton
Background technology
Planting cotton growing seedlings adopts soil surface heating agent to grow seedlings in the past usually, because organic matter is seriously polluted, utilize transparent plastic film to grow seedlings so far from the eighties, because residual of film can not be died away, cause residual of film in the plow layer cumulative, have a strong impact on the gas permeability and the water penetration of soil, influence the growth of farming and plant.The degradable film of having developed is difficult to promote the use of for outlying poverty-stricken area owing to the price height.For residual of the film that overcomes in the plow layer continues the accumulation problem, for improving the germination rate of cottonseed, need to increase soil temperature and moisture simultaneously.
The present invention is according to the problem of present existence, the method of a kind of drip irrigation with warm water kind cotton is provided, this method is sprouted moisture content, heat and the air that needs in the soil according to cottonseed, utilize warm water to adopt the mode of irrigate band, sprout the moisture content in the needs soil, the requirement of heat to satisfy cottonseed, grow seedlings thereby substituted the plastic film covering, overcome the residual problem that continues accumulation of film in the plow layer.
Summary of the invention
The object of the invention is, the method of a kind of drip irrigation with warm water kind cotton is provided, this method sows cottonseed at bottom of trench, in the adjacent bottom of trench of cottonseed, lay the irrigate band, adopt drip irrigation with warm water, sprout the moisture content in the needs soil, the requirement of heat to satisfy cottonseed, grow seedlings, overcome the residual problem that continues accumulation of film in the plow layer thereby substituted the plastic film covering.
The method of a kind of drip irrigation with warm water kind cotton of the present invention follows these steps to carry out:
A, with cottonseed sowing at bottom of trench, multiple fine earth flattens in fact, lays the irrigate band in the adjacent bottom of trench of cottonseed;
B, from being seeded into the employing drip irrigation with warm water of emerging, every 3-5 days drip irrigation once, the cotton back warm water of emerging continued drip irrigation 10 days, stopped drip irrigation with warm water when treating that surface temperature is stable and being raised to 20 ℃ ± 2 ℃, used general water droplet instead and irritated.
The multiple fine earth 2-5cm of step a.
20-30 ℃ of step b water temperature.
Embodiment
Embodiment
Field test station, Aksu, Xinjiang, spring irrigation 40cm profundal zone after the beginning of March soil thaws, April, early and middle ten days was ploughed rake, water furrow planting, at bottom of trench, multiple fine earth 2-5cm flattens real with the cottonseed sowing, and in the adjacent bottom of trench of cottonseed, lay the irrigate band, the sowing cottonseed carries out for intersecting with the line-spacing of laying the irrigate band;
One end of irrigate band is located in the pump house in field, water is heated water temperature 20-30 ℃ in pump house, carry out drip irrigation by the irrigate band, to improve the temperature and the moisture of soil, emerge about about 20 days from being seeded into, adopt drip irrigation with warm water, every 3-5 days drip irrigation once, according to soil moisture content, can grasp flexibly, warm water continued drip irrigation 10 days to treat to emerge afterwards by cotton, when face of land temperature stabilization is raised to 20 ℃ ± 2 ℃, stop drip irrigation with warm water, use general water droplet filling instead and get final product.
Adopt method of the present invention, through the use at field test station, Aksu, Xinjiang, the emergence rate of cotton is 99.9%, thereby has substituted the covering of plastic film, has solved the pollution problem in the plow layer.
Claims (3)
1. the method for a sowing cotton by drip irrigation with warm water is characterized in that following these steps to carrying out:
A, with cottonseed sowing at bottom of trench, multiple fine earth flattens in fact, lays the irrigate band in the adjacent bottom of trench of cottonseed;
B, from being seeded into the employing drip irrigation with warm water of emerging, every 3-5 days drip irrigation once, the cotton back warm water of emerging continued drip irrigation 10 days, stopped drip irrigation with warm water when treating that surface temperature is stable and being raised to 20 ℃ ± 2 ℃, used general water droplet instead and irritated.
2. method according to claim 1 is characterized in that the multiple fine earth 2-5cm of step a.
