Description

A kind of method of sowing cotton seed

Technical field:

The present invention relates to proportion of crop planting technical field, be specifically related to a kind of method of sowing cotton seed.

Background technology:

Cotton, is the seed fiber of Malvaceae cotton, originates in subtropics.Plant shrub shape, in torrid areas, cultivation can grow to 6 meters high, is generally 1 to 2 meter.Flower milky, changes into soon peony and then withers after blooming, leave green small-sized capsule, is called cotton boll.In cotton boll, have cottonseed, the fine hair on cottonseed grows from cottonseed epidermis, fills up cotton boll inside, and cotton boll splits when ripe, exposes soft fiber.Fiber white or white middle band are yellow, are about 2 to 4 centimetres, containing cellulose approximately 87～90%.

And in the period of sowing cotton seed, there will be big and small problem, in sowing, to use diverse ways according to the situation of environment, weather, land fertility, seed self, but method is now all similar, although such method there will not be too large problem in the process of using, but the situation that often just there will not be fecund, high yield, does not so just reach good effect.

Summary of the invention:

Technical problem to be solved by this invention be to overcome existing technological deficiency provide a kind of method rationally, carry out convenient, sowing a kind of method of sowing cotton seed easily.

Technical problem to be solved by this invention adopts following technical scheme to realize:

A method for sowing cotton seed, is characterized in that: comprises the following steps,

Step 1, broadcast front preparation:

1.1, fertilizer spraying: the ground moisture creating of spreading and sinking in for 10-15 days prior to seeding;

1.2, fertilising: use compound potassium sulfate fertilizer 30-40kg for every mu, in conjunction with whole disposable bottom application;

1.3, meticulous whole ground: while adopting spring ploughing mode, topsoil depth is 15-20cm, will harrow in time lid after ploughing, and accomplishes that soil is in small, broken bits, upper warm and sunny lower reality, Land leveling;

Step 2, seed selection breeding and seed treatment:

2.1, select breeding: select resistance to insects, disease resistance, yielding ability preferably in ripe or late variety;

2.2, seed treatment: hair seed or dressing seed will shine 2-3 days at fine day prior to seeding;

Step 3, proper seeding:

3.1, starting sowing 15-23 day in April, or adopting plastic mulching, in sowing by the end of April;

3.2, seeding method and the amount of broadcasting:

3.2.1, machine sowing: mu is broadcast 1.5-2kg;

3.2.2, artificial seeding: mu is broadcast 1-1.5kg, every bunch planting 2-3 grain;

Step 4, suitable seed level: sowing depth is 2.5-3cm;

Step 5, plastic mulching: first sowing, covering film then, do mechanization operation;

Step 6: broadcast rear management: check in time to have or not broadcast leakage, Cancellation Missed, fall to do and the situation such as rotten kind, will reseed in time after discovery, guarantee that Miao Qimiao strengthens.

Beneficial effect of the present invention is: very simple, easy-to-understand of above-mentioned step, and very clear, be applicable to specialty or common staff's reference and use, and the sowing time, with very clear all such as pesticide volume.The inventive method is reasonable, implementation is convenient, it is convenient to sow.

Embodiment:

For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below further set forth the present invention.

A method for sowing cotton seed, is characterized in that: comprises the following steps,
