Abstract

The invention discloses the latest wet rice seedling direct sowing technology. The technology comprises the following steps of: plowing mud in a field in which rice is to be planted by using a rotary cultivator to ensure that the mud naturally flows and is in a horizontal state after being settled, and applying 25kg of rice special fertilizer to each mu of field in the plowing process; sowing within half a month before snow is stopped and ensuring that 4 to 7 days after sowing are sunny generally (note: by watching weather prediction of China central television); sowing 0.75 to 1kg of seeds in each mu of field generally; soaking in 50 DEG C warm water for 48 hours before sowing; frying rice grains in an amount which is two times that of the seeds by using a pot, ensuring that the fried seeds cannot grow into seedlings or germinate, and soaking in a pesticide for half a day or more (in order to prevent the sown seeds from being damaged); uniformly mixing the soaked seeds and the rice grains soaked in the pesticide during sowing, and choosing a sunny day; wearing cotton gloves on hands during sowing, dipping the seeds, and forcibly and uniformly sprinkling forwards and upwards; and keeping 3 to 4cm of vertical water in the field for a long time after sowing.

Description

Up-to-date paddy rice water seedling direct seeding technique

One, affiliated technical field:

The present invention relates to the technical problem of the up-to-date water seedling of agricultural rice direct seeding technique, especially can reach high yield, send out root and stem of certain plants power strong, reduce labour's intensity and play conclusive effect.

Two, background technology:

Present known rice growing technology has two kinds: the one, and water seedling seeding technique, the 2nd, native seedling seeding technique.

1, water seedling sowing: it generally is sowing or the sowing before the Spring Equinox about first half of the month of disconnected snow.Annotate: (our area generally is the frost that breaks in clear and bright disconnected snow, grain rains); Be not to be processed into 4 chis in the field by the winter of a steady water---the railway carriage or compartment, railway carriage or compartment that 4.2 chis are wide; Catch up with the seed of flat planting to it, its rare density is: and 4 chi to 4.2 chis are wide * and long sowing 125 grams of 10 chis are to 150 gram seeds, encircle upper film then; Through management, just transplant at last.

2, native seedling sowing: it generally is the sowing about previous month of disconnected snow, or sows about the Waking of Insects (3rd solar term), is dried field or the soil that does not have water resource by one.Dig carefully, dig flat, fertilising to it, make the wide railway carriage or compartment, railway carriage or compartment of 4 chi to 4.2 chis, sowing then, its rare density is: about long sowing 150 grams of 4 chi to 4.2 chis * 10 chis; After broadcasting, fine earth on the face is executed farmyard manure on seed; Encircle upper film again and form,, transplant again then through management.

Three, summary of the invention:

In order to overcome the seedling process of doing that existing rice growing technology is done rice seedling bed, sowing, management, transplanted this complicated procedures of forming.The present invention provides a kind of up-to-date rice direct-seeding technology, and this technology can not only solve existing do paddy rice water seedling and this complicated course of work of native seedling.And can reduce a lot of labours, and improve output, it is strong to send out root and stem of certain plants power, is the best rice growing technology of family that does not have the labour.

Technical scheme: the technical solution adopted for the present invention to solve the technical problems is:

1, before the sowing, at first plough machine to the field that will plant paddy rice with whirlpool and plough out mud to it, estimate that mud flows through nature, every mu of underground 50 jin of paddy rice-dedicated fertilizers in the time of farming simultaneously become level after the deposition.

2, the sowing time: generally within preceding 7 days of disconnected snow to two weeks, the fine 4-7 of tail days with upper seeding wheel.(annotate: this sees the weather forecast of central TV station)

3, type of seeding: at first press the seed planned what, general every mu of ground is 1.5 jin to 2 jin seeds.With 50 degree emerge in worm water 48 hours just.It makes popular the meal paddy that also doubles in addition with hingle, and estimation can not be given birth to seedling and germinateed and get final product, and then with agricultural chemicals immersion half a day or more than half a day (this prevent the seed that broadcasts be injured).In sowing, just mix soaked seed and the meal paddy of having soaked agricultural chemicals in addition, mixing is chosen fine day then, preferably sows to the weather more than 7 days in fine 4 days continuously.Hand will be put on line gloves during sowing, is stained with ready seed then and exerts oneself to be with forward upwards to spill, and spills evenly just, and the field will keep the upright water of 3-4 centimetre for a long time after sowing in addition.A people can sow 10 mu every day more than the ground.

Beneficial effect: the invention has the beneficial effects as follows: reduce this link do rice shoot, transplanting seedlings not, it is strong to send out root and stem of certain plants power, and output is high, and seed spills through management and just can gather in, and method is simple.

Four, practical implementation method:

Claims

1. a up-to-date paddy rice water seedling direct seeding technique is: plough machine with whirlpool and go out mud, fertilising to the Tagayasu Den, estimate that mud flows through nature, become level after the deposition, the fine sowing within first half of the month of disconnected snow.With 50 degree emerge in worm water seeds.As many again meal paddy is made popular, mixes agricultural chemicals, it's time to then sow; The meal paddy mixing of seed and mixed agricultural chemicals is put on line gloves with hand then, is stained with seed and firmly upwards spills forward; Spill evenly, it is characterized in that: after the sowing, keep 3 to 4 centimeters upright water for a long time.

2. up-to-date paddy rice water seedling direct seeding technique according to claim 1.It is characterized in that: plough machine with whirlpool and go out mud to the Tagayasu Den, estimate that nature flows, and becomes level after the deposition.

3. up-to-date paddy rice water seedling direct seeding technique according to claim 1.It is characterized in that: seed soaks to make popular with meal paddy after good and has soaked agricultural chemicals and mix afterwards, and it is even to be mixed.

4. up-to-date paddy rice water seedling direct seeding technique according to claim 1.It is characterized in that: put on line gloves with hand, be stained with mixed seed and exert oneself to be with forward upwards to spill, spill evenly.

5. up-to-date paddy rice water seedling direct seeding technique according to claim 1.It is characterized in that: the field will keep 3 to 4 centimeters upright water for a long time after the sowing.

6. up-to-date paddy rice water seedling direct seeding technique according to claim 1.It is characterized in that: in the fine sowing within first half of the month of disconnected snow.
