Description
Technical field
The invention belongs to rice cultivating technique fields, specifically, being related to a kind of paddy rice planting method of control Weedy Rice.
Background technology
Rice is China's staple food crop, and China has 60% or more population using rice as staple food.Rice total output improves
Also improve the living standard of our people.The Monitoring of Paddy Rice Plant Area in China is wide, planting season is various.The planting patterns of rice from
Great change has occurred since the seventies in last century.Socio-economic development and country labor force transfer, Rice Cropping is from transplanting rice seedling by hand
Transplanting, live streaming transition to dart transfer.In recent years, various regions are under the support and promotion of policy, and rice planting technology area is
Through accounting for critical role.However, rice mechanized transplant content is high, need seedling and the machine transplanting of rice, relative cost higher.In recent years, due to water
Rice productivity effect is not high, and main rice belt rice farmer is cost-effective using direct sowing of rice.However, after live streaming in several years, mostly
There is Weedy Rice in varying degrees in rice field, and some has been caused disaster, and the more serious underproduction is caused to rice farmer, and rice quality declines,
Rice Production benefit is caused to decline to a great extent.
Weedy Rice is also named red rice because its grain of rice is mostly red rice.Weedy Rice occurs in direct sowing rice field mostly, and China is close
The rice field of Nian Yinyou is broadcast live year after year to happen occasionally.4-5 is continuously broadcast live in general rice, it is possible to Weedy Rice occurs.Weedy Rice
Identical as rice type, common herbicides for use in paddy cannot be by it except extremely, control difficulty is big, and increases year by year.
Invention content
In view of this, the present invention provides a kind of paddy rice planting methods of control Weedy Rice.
In order to solve the above-mentioned technical problem, the invention discloses a kind of paddy rice planting methods of control Weedy Rice, including with
Lower step：
Step 1, site preparation and fertilising：The cultivated site preparation of 2-3 weeks machinery before plantation, field arrange, machine consistent with conventional machine transplanting of rice field
Basal dressing before inserting, and carry out weeding processing；
Step 2, vernalization and sowing：Using the clever Medicament soaked seed of seed soaking and vernalization processing, and use seedling-cultivation plate；
Step 3, seedling：Seedling disk, which is placed in greenhouse, carries out disc stack emergence seedling, in due course water management, diseases prevention insect prevention；
Step 4, the machine transplanting of rice：The seedling tep reel machine transplanting of rice from when rice reaches the length of time rice seedlings grow；
Step 5, in the tiller middle and later periods, using manually pulling out；At heading stage, using manually pulling out or cut off；In rice
Weeds are removed totally before into the phase of blossoming and bearing fruit；
Step 6, field management：Field management is carried out using conventional method.
Optionally, the weeding in step 1 is specially：1-3 centimetres of field moistening or water layer are kept, Weedy Rice and weeds are promoted
Germination；4-5 days before Rice Cropping, Weedy Rice and weeds are killed using steriland herbicide, using steriland herbicide
Field needs to drain, the machine transplanting of rice after pouring water；If killing Weedy Rice and weeds, the 2- before Rice Cropping using mechanical rotary tillage method
Farming in 3 days.
Optionally, the seed soaking time in step 2 is 45-50h；Germination temperature is 32-38 DEG C, germination time 20-28h.
Optionally, the size of the seedling disk in step 2 is 9 cun, and each seedling disk sows 60~70 grams of seeds of hybrid paddy rice, conventional Rice
100~120 grams of seeds.
Optionally, 25~30 days south early rice length of time rice seedlings grow, the single harvest rice and the late rice length of time rice seedlings grow 20-25 when machine transplanting of rice in the step 4
It, the 30-35 days northern length of time rice seedlings grow, machine transplanting of rice density mu inserts hybrid paddy rice 1.0-1.4 ten thousand clumps, conventional Rice 1.5-2.0 ten thousand clumps.
Optionally, same rice field uses machine using direct sowing of rice and machine transplanting of rice rotation, 3 years using live streaming, later 2-3
It inserts.
Compared with prior art, the present invention can be obtained including following technique effect：
1) present invention uses rice planting technology mode, can effectively control hybrid paddy rice.Direct-seeding planting is such as used, is hybridized in order to control
Rice, after direct sowing of rice 2-3, wheel is changed to rice mechanical transplanting, effectively solves surviving and breeding for weeds rice, and realizes straight
Broadcasting rice reduces production cost, and solves the Weedy Rice harm that Direct-seeding Rice is brought, this is the agronomy controlling party of Weedy Rice green ecological
Method, and realize the sustainable production of rice.
2) whole field of first pouring water can be used under paddy growth season admissible condition in the present invention, keeps field 1-3 cm of water
Layer, after Weedy Rice germination and emergence, is killed Weedy Rice using mechanical rotary tillage or steriland herbicide.Big portion can be killed in this way
Divide Weedy Rice.
3) present invention is in the serious field of Weedy Rice, and the autumn fields after rice harves not ploughed deeply, and controlling weeds rice is turned over
Enter deep soil, difficulty is brought to later Weedy Rice control.
Certainly, it implements any of the products of the present invention it is not absolutely required to while reaching all the above technique effect.
Specific implementation mode
Carry out the embodiment that the present invention will be described in detail below in conjunction with embodiment, thereby to the present invention how application technology hand
Section solves technical problem and reaches the realization process of technical effect to fully understand and implement.
The invention discloses a kind of paddy rice planting methods of control Weedy Rice, include the following steps：
