Abstract

The present invention realizes the optimization that process is sowed during to rice growing by using wetting seeding technique, reduces cost during rice growing, adds the lodging resistance of paddy rice, reduces the practical amount of agricultural chemicals, adds the yield of paddy rice.It is specific to add cyhalofop-butyl and anilofos to carry out cauline leaf spraying with pretilachlor bensulfuron-methyl in the heart stage of one leaf of paddy rice one to have reached the purpose of the present invention by the seed dressing before rice growing, the setting of water layer and rational selection.

Description

A kind of paddy rice soaks type of seeding

Technical field

The present invention relates to a kind of farming method, and in particular to a kind of method of rice growing.

Background technology

With expanding economy, peasant is progressively changed for the cultivation of paddy rice from traditional culturing and transplanting seedlings to directly sowing, The directly sowing of current paddy rice is divided into：Water direct seeding and direct-sowing dry, the whole field of water direct seeding are very laborious time-consuming, it is necessary to be beaten repeatedly with beater Slurry, it is that soil permeability is deteriorated to be beaten the negative results brought, and root system is undeveloped；Direct-sowing dry is easy to operate, but weeding difficulty Greatly.

The content of the invention

In order to overcome the respective shortcoming of institute's water direct seeding or direct-sowing dry during current rice growing, the invention provides a kind of energy Brand-new direct-seeding-wetting direct-seeding of the defect of water direct seeding and direct-sowing dry is enough overcome simultaneously, passes through the leather to direct-seeding It is new to reach increase Paddy Output, the effect of reduction sowing difficulty.Direct-seeding, existing water direct seeding are soaked the invention provides one kind Easily, the permeability of direct-sowing dry soil its specific operating method is maintained again is for weeding：First quarter moon before planting, field is pernicious What weeds had emerged, cauline leaf process is carried out with glyphosate or glufosinate-ammonium, if field grassy weed is in the majority, essence can also be added Quizalofop-ethyl or clethodim spraying treatment.Rice field keeps moistening or 2CM or so water layer during sowing, and rice seed vernalization to broken chest shows money or valuables one carries unintentionally, Dressed seed with carbosulfan, then with the shallow rotation sowing of rotary tillage program request all-in-one rotary tillage,（Connect the sowing of rotary tillage band）, can also be one time Manually the direct of the seed for mixing seed dressing is broadcasted sowing on the native face of moistening after rotary tillage, ground moistening is kept；Weeding Mode has two kinds：One kind is that an inside front cover is killed；With traditional water direct seeding weeding scheme.Another is closing weeding and after seedling herbicide one It is secondary to complete；Collective's way is：Cyhalofop-butyl and anilofos cauline leaf is added to spray in paddy rice one leaf, one heart stage pretilachlor bensulfuron-methyl, Medication effect twice can once be reached, it is necessary to now with the current.

Beneficial effect

Compared to traditional direct-seeding, the present invention is in the rice field of moistening, it is only necessary to which a rotary tillage can be sowed, and reduce one Secondary mechanical work, field is not especially smooth, even if the field soil cultivated has some soil blocks not of uniform size to adopt With the seeding method of the present invention, exactly because the present invention's cultivates method only rotary tillage or is beaten once, thus the meeting in rice field Form many spaces not of uniform size, paddy rice dry field when, the oxygen content in soil increases compared to the oxygen content of water direct seeding Plus, promote rice root vigor to greatly increase, root system is more flourishing, lodging resistance is just improved than water direct seeding, such paddy rice is not Meeting early ageing, so as to increase on the whole per per mu yield.Because there is soil block not of uniform size in field, earth's surface over time Soil block can all be gone to sticks and staves, and rice shoot root can be buried in 1-2CM soil layer, be added the lodging resistance of crop, and not influence tiller. Because field can keep moistening during weeding, herbicidal effect is more preferable than direct-sowing dry, and the present invention, can be with a leaf wholeheartedly weeding Planting household is lacked with a weeding, also just reduce once artificial.

Embodiment

1st, 300 mu of paddy rice are planted with moistening seeding technique, in the first half of the month of rice growing, is entered with glyphosate or glufosinate-ammonium Row cauline leaf process；Rice field keeps 2CM or so water layer during sowing, and rice seed vernalization to broken chest shows money or valuables one carries unintentionally, dressed seed with carbosulfan, so Afterwards with the shallow rotation sowing of rotary tillage program request all-in-one rotary tillage, that is, connect the sowing of rotary tillage band；In the heart stage of one leaf of the paddy rice one phonetic sulphur of pretilachlor benzyl Grand plus cyhalofop-butyl and anilofos carry out cauline leaf spraying, and the pretilachlor bensulfuron-methyl adds cyhalofop-butyl and anilofos now to match somebody with somebody Now use；By soaking the rice field that live broadcasting method is sowed, every mu average compared to water direct seeding is increased production 51 kilograms, than direct-sowing dry herbicide Less with 20 yuan every mu.

2nd, using 200 mu of seeding technique rice cultivation of moistening, in the first half of the month of rice growing, field malignant weed is Emerge, cauline leaf process is carried out with glyphosate or glufosinate-ammonium；Rice field keeps moistening during sowing, and rice seed vernalization to broken chest shows money or valuables one carries unintentionally, Dressed seed, manually the seed for mixing seed dressing is directly broadcasted sowing on the native face of moistening with carbosulfan after a rotary tillage, protected Hold ground moistening；Cyhalofop-butyl and anilofos are added to carry out cauline leaf spray with pretilachlor bensulfuron-methyl in the heart stage of one leaf of paddy rice one Mist, the pretilachlor bensulfuron-methyl adds cyhalofop-butyl and anilofos must be now with the current；Average every mu more public than water direct seeding volume increase 63 Jin, every mu average than direct-sowing dry few with 25 yuan every mu of herbicide.

Claims

1. in the first half of the month of rice growing, field malignant weed has been emerged, carried out with glyphosate or glufosinate-ammonium at cauline leaf Reason；If in the first half of the month of rice growing, field grassy weed is in the majority, plus Quizalotop-ethyl or clethodim spraying treatment.

2. rice field keeps moistening or 2CM water layers during sowing, rice seed vernalization to broken chest is showed money or valuables one carries unintentionally, and seed dressing is used as with carbosulfan Seed dressing, then with the shallow rotation sowing of rotary tillage program request all-in-one rotary tillage, or manually the seed for mixing seed dressing after a rotary tillage Directly broadcast sowing on the native face of moistening, keep ground moistening.

3. add cyhalofop-butyl and anilofos to carry out cauline leaf spraying, third grass with pretilachlor bensulfuron-methyl in the heart stage of one leaf of paddy rice one Amine bensulfuron-methyl adds cyhalofop-butyl and anilofos must be now with the current.
