Abstract

The invention discloses a paddy no-tillage direct seeding method which is high in paddy scion rate, high in yield, high in milled rice rate, superior in rice quality, and saving in labor, fertilizer and water, and belongs to the technical field of crop culture. According to the method, before the winter solstice, weed killer is sprayed for killing weeds, and the land surface is naturally frozen; weed killer is sprayed again around the tomb-sweeping Day of the next year, and after the weeds are dead, the land is irrigated to keep humidity, and non-grown weeds grow again; weed killer is sprayed the third time around the Beginning of Summer, after the weeds are dead 7 days after weed killer spraying, the land is irrigated continuously for soaking about 6-8 days; seed-corns are soaked in lime water until the seed-corns sprout, then are fished up after being soaked for 10 hours, then rooting powder is mixed with sprouted seed-corns, and after the mixed sprouted seed-corns are aired for 1-3 hours at a shade place, the seed quantity for each mu is 8-10 jin of common variety, and about 3 jin of hybrid seeds; weed killer is sprayed for killing weeds within 1-2 days after sowing in the mode that sealed non-sprouted seeds are made to grow until having 3-4 leaf ages, water in the land is released completely and then the land is sealed to clean the weeds; nitrogen phosphorus and potassium fertilizer is dressed 3-4 days after weed killing; then normal field management period is started.

Description

Paddy rice no-tillage and direct-seeding method

Technical field

The present invention discloses a kind of method of Rice Cropping, specifically, is a kind of paddy rice no-tillage and direct-seeding method; Belong to crops culture technique field.

Background technology

Paddy rice no-tillage and direct-seeding refers in results after a season crop rice field without any plow harrow of turning over, first use steriland herbicide to go out to cut weeds and shattering paddy seedling, urge withered rice stub, fill with deep water waterlogged plot, after water layer falls dry, basal dressing naturally, the rice paddy seed that vernalization shows money or valuables one carries unintentionally is directly seeded into a kind of rice cultivating technique of grown in field.But at present, there is following problems in paddy rice no-tillage and direct-seeding: conventionally occurs rotten kind or burn bud, cause and be short of seedling, the inequality of emerging, tillered nursery plant peak early, high pin seedling, the percentage of earbearing tiller is low, number of grain per ear is on the low side, the problems such as crop smothering and lodging easily occurs, and then affect output, give like this agricultural producer, brought very large puzzlement.

Summary of the invention

For the problems referred to above, the object of the present invention is to provide a kind of paddy rice no-tillage and direct-seeding method, the paddy rice knot fringe rate that adopts the method to plant is high, and rice is of fine quality, and saving is artificial, and province is fertile, water-saving.

For solving the problems of the technologies described above, technical scheme provided by the invention is such: this paddy rice no-tillage and direct-seeding method, comprises the steps: successively

1) weeding

Before Winter Solstice, first with surface, weed killer herbicide weeding ，Rang soil, naturally freeze soft; Spray herbicide weeding again before and after the 2nd year Ching Ming Festival, allows weeds after death, and pouring keeps field moistening, allows the weeds not germinateing regenerate; Spray herbicide weeding again before and after the Beginning of summer, weeding, after 7 days, allows weeds after death, and 6-8Tian，Rang soil, continuous pouring soil soaks deliquescing;

2) seed-grain is immersed in limewash and picks up vernalization about 10 hours, then with root-inducing powder, mix the seed-grain of germination, allow seed take root fast well, shady and cool place's airing is after 1-3 hour, by the 1. conventional variety 8-10 jin sowing of the seeding quantity of every mu of seed, 2. Hybrid seeding quantity is 3 jin of left and right;

3) broadcast sowing in latter 1 to 2 day and use seeding bed herbicide weeding, the weeds that germinate in sealing end, anti-regeneration length;

4) when rice shoot grows to 3 to 4 ages, put dry Tanaka's water, with herbicides for use in paddy, weed a garden;

5) weeding imposes azophoska later for 3 to 4 days;

6) after this enter normal field management.

Above-mentioned paddy rice no-tillage and direct-seeding method, the weed killer herbicide described in step 1) is Glufosinate.

Further, above-mentioned paddy rice no-tillage and direct-seeding method, 8.8 jin every mu of described planting seed amounts.

Compared with prior art, technical scheme provided by the invention is groped through field planting in a few years, strict each planting link of optimizing, obtain best paddy rice no-tillage and direct-seeding method, the method repeatedly adopts weed killer herbicide weeding, avoided in prior art paddy rice no-tillage and direct-seeding weeds more, crop smothering problem serious and that pay, with limewash, soak seed-grain and pick up rear vernalization, then with the seed-grain that root-inducing powder is mixed germination, avoided the rotten kind of common appearance or burnt bud, cause and be short of seedling, the unequal problem of emerging, method paddy rice knot fringe rate provided by the invention is high, rice is of fine quality, save artificial, economize fertile, water-saving, output is high, go out polished rice rate high.

Embodiment

Below in conjunction with embodiment; claim of the present invention is described in further detail; but do not form any limitation of the invention, the modification of any limited number of time of making within the scope of the claims in the present invention, still within claim protection domain of the present invention.

Embodiment 1

A kind of paddy rice no-tillage and direct-seeding method provided by the invention, comprises the steps: successively

1) weeding

First before Winter Solstice, surface, spray Glufosinate weeding ，Rang soil naturally freezes and becomes bubble; Before and after the 2nd year Ching Ming Festival, again spray Glufosinate weeding, allow grass after death, pouring keeps field moistening, allows the weeds not germinateing regenerate; Before and after the Beginning of summer, spray Glufosinate weeding, weeding, after 7 days, allows grass after death again, continuous pouring soil 6-8 days, and preferably 7 Tian，Rang soils are macerated, and are convenient to rice sprout and take root;

2) seed-grain is immersed in limewash and extremely germinates, then with root-inducing powder, mix the seed-grain of germination, airing was located after 1-3 hour in cool place, and preferably 2 hours, by the seeding quantity 8-10 jin of every mu of seed, sow, 1. best seeding quantity is 8.8 jin, 2. 3 jin of left and right of Hybrid;

3) broadcast sowing the weeds regrowth of germinateing with seeding bed herbicide sealing end in latter 1 to 2 day;

4) when rice shoot grows to 3 to 4 ages, put dry Tanaka's water, with herbicides for use in paddy, weed a garden, as weeds such as very heavy seed and barnyard grasses;

5) weeding imposes azophoska later for 3 to 4 days;

6) after this enter normal field management.

The technical scheme that invention provides is groped through field planting in a few years, strict each planting link of optimizing, obtain best paddy rice no-tillage and direct-seeding method, the method repeatedly adopts weed killer herbicide weeding, avoided in prior art paddy rice no-tillage and direct-seeding weeds more, crop smothering problem serious and that pay, with limewash, soak seed-grain to germinateing, then with the seed-grain that root-inducing powder is mixed germination, avoided the rotten kind of common appearance or burnt bud, cause and be short of seedling, the unequal problem of emerging, method paddy rice scion rate provided by the invention is high, rice is of fine quality, save artificial, economize fertile, water-saving, output is high, go out polished rice rate high.
