Abstract
The invention relates to a method for improving seedling rate of wheat-residue to field launching direct seeding rice, and the method comprises the steps of selecting plump rice seed by drifting with sodium chloride aqueous solution after drying the rice seed; then taking prochloraz missible oil and imidacloprid wettability pulvis, adding water and stirring uniform, then adding benzoic acid and abscisic acid and stirring uniform again to get the medicament; soaking the selected plump rice seed after drifting in the medicament for 36-48h; paving the rice seeds uniformly after soaking and the paving thickness is between 20-30cm; covering a straw curtain; accelerating germination until the bud length is 1/2 of the rice seed length; and planting the seed after airing to the full wheat-residue to field. According to the invention, the seedling rate can be raised by 25%; the insect disease in the seedling stage is obviously decreased; 0.5-1.0 per plant tillering is increased comparing to common sowing method; turning green is 1-2d earlier after transplanting; the stress resistance is enhanced; full and strong sprout are promoted; and water direct seeding rice output is effectively improved.
Description
Technical field
The present invention relates to rice direct-seeding technical field, specifically a kind of method improving Direct-sowing rice planting percent under wheat straw returning.
Background technology
In recent years, along with a large amount of transfer and the light development simplified of cultivation of rural laborer, the area development of Direct-seeding Rice rapidly.China's Direct-seeding Rice area has reached 2,000,000 hm
2, in In Middle And Lower Reaches of Changjiang River, cultivated area is in the trend obviously risen.According to incompletely statistics, Jiangsu Province in recent years Direct-seeding Rice application in coming year area has reached more than 1/3 of Monitoring of Paddy Rice Plant Area, has become first rice make mode in some areas.Wheat straw is a kind of energy substance containing carbon rich, both containing nutritive elements such as a considerable amount of carbon, nitrogen, phosphorus, potassium, there is again the effects such as the physico-chemical and biological properties improving soil, it is one of important organic source of environmental protection, but in production practices, wheat straw is not used effectively, peasant is in order to rob farming season, save manpower, frequent way is directly burned by a large amount of agricultural crop straws, this not only causes the wasting of resources and environmental pollution, and causes adverse effect to agricultural soil fauna, and causes huge economic loss.
Direct-seeding Rice generally requires relatively high to seeding technique, and soil characteristics has obvious impact to seedling simultaneously.In recent years, along with the progressively increase of straw-returning, a large amount of noxious material is discharged in straw decomposition process, there are some researches show, the materials such as a large amount of benzoic acid, forulic acid, p-aminobenzoic acid are discharged in wheat straw decay process, simultaneously stalk itself is with a large amount of pathogenic bacteria, therefore low, the dead seedling of Direct-seeding Rice seedling quality, be short of seedling, the low inferior phenomenon of planting percent occurs repeatedly, become the outstanding problem restricting direct seading rice high yield.Therefore improve the resistance of rice shoot, guarantee direct seading rice seedling, strong sprout, to realizing, direct seading rice good quality and high output is significant.Have not yet to see and can improve full dose wheat straw returning (7.2-7.6t/ha), the method for Water Under Direct-seeding Rice seedling.
Summary of the invention
The present invention seeks to as solving to solve full dose wheat straw returning, namely Straw Weight of Wheat Return be that the Water Under Direct-seeding Rice planting percent of 7.2-7.6 ton/hectare (t/ha) is low, planting percent and the not high problem affecting paddy rice economic benefit of seedling quality, a kind of method improving condition Direct-sowing rice planting percent under wheat straw returning is provided, method is simple, with low cost, seed planting percent can be improved, land for growing field crops nutrition condition can be improved again.
Improve a method for Direct-sowing rice planting percent under wheat straw returning, comprise the following steps:
(1) to bask seeds seed selection: after rice seed is shone 4-5h in the sun, load in bucket, adding density is 1.05 ~ 1.10g/cm
3sodium-chloride water solution winnow, remove the flat rice grain of supernatant sky, retain heavy underwater full rice grain; By the full rice grain by retaining after density seed selection, rinse well with clear water, for subsequent use;
(2) preparation of medicament: often prepare 6-8kg medicament, get 2ml mass fraction be 25% make hectogram missible oil and 10g mass fraction 10% imidacloprid wettable powder, add 6-8kg water, adding whole mass percent concentration after stirring is the benzoic acid of 0.1% and the abscisic acid of 0.3ppm, again stir and namely obtain 6-8kg medicament, for subsequent use;
(3) soak seed: according to the standard of adding the rear full rice grain retained of 4-5kg density seed selection in every 6-8kg medicament, the full rice grain retained after density seed selection is joined in prepared medicament, stir after stirring up and down, seed soaking 36-48h, rice grain after having soaked seed, for subsequent use;
(4) evenly tiled by the rice grain after having soaked seed, thickness is 20-30cm, covers straw screen or mat, and vernalization to bud length is 1/2 of Grain Length in Rice, and airing is waited to sow;
(5) rice grain after vernalization is sowed in the rice field (namely Straw Weight of Wheat Return is the rice field of 7.2-7.6t/ha) of full dose wheat straw returning, then conventionally manage.
More preferred, temperature of basking seeds described in step (1) is 25-30 DEG C.
More preferred, described in step (3), the temperature of seed soaking is 20-25 DEG C.
Beneficial effect is: the method energy significance that the present invention improves Direct-sowing rice planting percent under wheat straw returning improves rice paddy seed planting percent, and planting percent on average improves 25%; The method can make rice seedling damage by disease and insect obviously alleviate, and more common type of seeding individual plant is tillered increases 0.5-1.0, early 1-2d of turning green after rice transplanting, and resistance strengthens; And the inventive method can promote full stand and strong sprout, effectively improve the output of Direct-sowing rice.
