Abstract

The invention provides a rice direct seeding high yield planting technology, which comprising the following steps: choosing the land without industrial 'three wastes', namely, waste gas, waste water and industrial residue as the cultivation land; applying enough organic fertilizer; choosing disease-resistant varieties; applying rice direct seeding technology; reasonably providing inorganic fertilizers and pesticides to ensure high yield of mature rice. The invention has the beneficial effect that the application of the invention in rice production guarantees high and stable yield of rice and income improvement of farmers.

Description

Rice direct seeding high yield planting technology

Affiliated technical field

The present invention relates to the culture technique of paddy rice, be particularly useful for the land for growing field crops and produce.

Background technology

At present, during many peasant planting paddy rice, cultivation method commonly used is the back field-transplanting of growing seedlings, and this cultivation mode labour intensity is big, perhaps mechanization degree require expensive greatly.Along with labour's transfer, press for a kind of new rice cropping pattern and replace, enhance productivity, reduce production costs.

Summary of the invention

In order to improve Rice Production efficient, to reduce production costs, the invention provides the new culture technique of a kind of paddy rice.

The present invention solves the technical method that its technical problem adopts: select not have the soil of industry " three wastes " as planting site, use sufficient fertilizer, select the strong kind of disease resistance, adopt the rice direct-seeding culture technique, rationally execute inorganic fertilizer and agricultural chemicals, guarantee ripe rice high yield.

Beneficial effect of the present invention is by the application of the present invention in Rice Production, to guarantee the paddy rice high and stable yields, peasant's income raising.

Specific implementation method

One, to select the kind that suits.Ripe middle stalk kind during Xu rice belongs to for No. 3, good quality and high output, strain shape compactness, early onset is good, and fertilizer resistance anti-lodging is strong, and high anti-stripe virus disease is guaranteed fully neat fringe.Suitable direct-seeding planting.

Two, good meticulous whole field.5-7 days behaviour fields of turning over before broadcasting, furrow were done in the harrow-like implement for pulverizing soil field in 2-3 days, 3.5 meters of furrow face widths, the furrow face will be put down, dark 30 centimetres of dead furrow, ditch is supporting unimpeded, it is clean that weeds are wanted.Preplant treatment fertilizer and inorganic fertilizer.

Three, planting early enough.Direct-seeding Rice is short breeding time, wants sowing in time after wheat harvest.Sowing more early helps high and stable yields more, strives that sowing finishes before June 10, can not surpass June 15 at the latest.

Four, Precision Seeding is even broadcasts.On the basis on meticulous whole ground, grasp the suitable amount of broadcasting.The mu sowing quantity is grasped and is advisable at the 4-5 kilogram, to guarantee rational colony starting point.The sterilization of basking seeds before broadcasting, soak seed, the direct-sowing dry not vernalization of generally only soaking seed.Accomplish the branch drill seeding kind during sowing, belt scale is gone to the field, and accomplishes not broadcast leakage, does not replay.After planting carry out artificial or machine cover seed, accomplish not reveal seed.

Five, science water pipe.Broadcast the back and must adhere to moisture management to 3 leaf phases, to promote taking root upright seedling, strive realizing the requirement in strong sprout of seedling early, full stand, even seedling, broadcast the back and in time carried out the field in 20-25 days and look into seedling and fill the gaps with seedlings, it is rare to move close benefit, the rice strain is evenly distributed, the individual growth balance.Alternation of wetting and drying behind the Qi Sui gathers in and cut off the water supply in preceding 7 days, and it is until old ripe to guarantee to live.

Six, the rational application of fertilizer.General mu is executed purity nitrogen 18-20 kilogram, phosphorus pentoxide 6-8 kilogram, and the ratio of accomplishing base manure, tillering fertilizer, fringe granulated fertilizer is 5: 3: 2.The modify-water face of answering on fertilizing method spreads fertilizer over the fields and is dry application, and shallow water is irritated in the fertilising back, realizes burying with water band fertilizer, reduces fertilizer loss, improves utilization rate of fertilizer.

Seven, eliminate early.Live field piece weeds time of origin early, kind is many, and crop smothering is serious, must eliminate early.Behind the premature rice 2-4 days, use U.S.'s Machete, convert the water weeding for 2 bottles every mu.The 2-4 leaf phase is used the butachlor weeding.To pull out perennial perennial root malignant weed early, reach the heading loose assorted rice of plant type early, prevent shattering.

Eight, gather in the crops in good time, prevent lodging.Direct-seeding Rice breeding time is about 140-150 days, results at the beginning of 11 months.

Claims

1. the present invention relates to the culture technique of paddy rice, it is characterized in that: the soil of selecting not have industry " three wastes " uses sufficient fertilizer as planting site, select the rice varieties of high yield, adopt artificial direct sowing culture technology, rationally execute inorganic fertilizer and agricultural chemicals, guarantee ripe rice high yield.
