Abstract

The invention relates to a high-yield paddy rice seedling-slinging cultivation method. The steps are as follows: (1) plots, the terrain of which is flat and which facilitate irrigation and drainage, are chosen as rice seedling plots, the germination of chosen paddy rice seeds is accelerated until sprouting, the paddy rice seeds are then put into seedling trays, the sprouted rice is covered by a layer of nutrient soil after being sowed evenly, and the thickness of the nutrition soil is determined according to that the embryos are not exposed; (2) before seedling slinging, soil is prepared finely, the plot surfaces are evened, and the seedlings are required to be slung after the soil is compact; (3) within 3 to 4 days after seedling slinging, the plot surfaces are not watered, the plots are irrigated deeply after 4 to 5 days, herbicide is applied, and the water layer is kept for 5 to 7 days; when the number of the seedlings approximates 80 percent of required ear number, water is drained and the plots are sunned, a shallow water layer needs to be kept during filling, and water is cut off 5 to 7 days before harvest; (4) after all the seedlings stand, herbicide and fertile soil are mixed and spread, and the water layer which is 3cm thick is kept in the plots for 5 to 7 days; (5) when all the seedlings stand, a tillering fertilizer is applied in combination with irrigation, 80kg to 100kg of urea is applied per hectare, 50kg to 70kg of urea is applied as an earing fertilizer at the initial stage of elongation, 3kg of monopotassium phosphate can be sprayed per hectare after full heading, and green-stem yellow ripeness, premature senility resistance and lodging resistance are achieved.

Description

Rice seedling throwing high-yield cultivating method

Technical field

The present invention relates to agricultural technology field, be specifically related to a kind of rice seedling throwing high-yield cultivating method.

Background technology

Paddy rice originates in Tropical Asian, after China widely plants, propagates into gradually all over the world.According to diverse ways, paddy rice can be divided into long-grained nonglutinous rice and japonica rice, early rice and middle late rice, glutinous rice and non-glutinous rice.The research of China scientist Yuan Longping to hybrid rice makes a great contribution, and is described as " father of hybrid rice ".The grain of rice that paddy rice is tied claims rice or rice after shelling.Nearly half population is in the world all food with rice.The eating method of rice is varied, has rice, congee, rice cake, rice cake, rice noodles rice wine etc.Paddy rice is except edible, and can also make wine, refine sugar and make the raw material of industry, rice husk, rice straw also have a lot of use.China paddy rice main producing region mainly the Northeast, the Yangtze river basin, Pearl River Delta.Paddy rice institute knot reality and paddy, claim rice or rice after shelling.Belong to direct economy crop.Or the staple food of the mankind.

And rice seedling throwing is the abbreviation that cultivation technology is thrown in the nursery of rice nutrition alms bowl, it combines the advantage of nursery and direct sowing culture, have and reduce labor intensity, save labour, alms bowl seedling does not hinder root, that slow seedling, root bury is shallow, tillering node is low, tiller many and the feature such as increasing both production and income.

Summary of the invention

It is low that technical problem to be solved by this invention is to provide a kind of cost, the simple rice seedling throwing high-yield cultivating method of method.

Technical problem to be solved by this invention realizes by the following technical solutions:

A kind of rice seedling throwing high-yield cultivating method, comprises following method step:

1) the nursery stage: select smooth, the irrigation and drainage of physical features easily field do rice seedling bed, after rice paddy seed after selected being broken bud to dew point, be placed in seedling-cultivation plate, Nutrition Soil is placed in seedling-cultivation plate, thickness 1.5cm, after broadcasting bud paddy equably, then cover one deck Nutrition Soil, thickness is not to reveal bud platform for degree; For preventing rice shoot string root, accomplish that seedling dish Middle nutrition soil is lower than aperture, card does not stay earth outside aperture; Requirement rice shoot is healthy and strong, and the length of time rice seedlings grow, band tiller rate was 100%, is advisable for every strain band tiller 2.5-3.5 at 40-45 days;

Described Nutrition Soil is made up of the component of following parts by weight: loess 100 parts, 5 parts, the mud in cellar for storing things, 5 parts, liver moss, natural pond slag 5 parts, sodium selenite 5 parts, seedling strengthen agent 1 part, mulberry leaf ash 5 parts, capsicum leaf ash 5 parts, humus soil 10 parts, 5 parts, liver moss, rice hull ash 10 parts, powder of straw 10 parts, 5 parts, vinasse, the pinecone 2 parts; All raw material classification sent in parcher during preparation, the parch time, parch moisture, at 15-20%, used 30 eye mesh screens to carry out pulverizing according to the humid control of different component at 5-20 minute in batches;

2) the rice transplanting stage: want that meticulous face, field is smooth wholely before rice transplanting, the not poor 2-3.5cm of height, every mu of organic fertilizer 500 kilograms, require soil heavy real after rice transplanting, throws in case dark, falls seedling, floating seedling, but sandy soil field will with whole with throwing; Rice transplanting 2-3 days does not fill with deep water, keeps shallow water;

Described fertilizer is formulated by the raw material of following component and consumption: nitrogenous fertilizer 10kg, natural pond slag 200kg, yellow sand 50kg, organic 50kg, humus soil 200kg, tealeaf residue 5kg, liver moss 5kg, colza cake 30kg, dregs of beans 3kg, corn stigma 3kg, amino acid 3kg, pinecone 30kg, ooze 20kg, ash wood 10kg, bagasse 20kg, vinasse powder 5kg;

3) water management: after throwing, in 3-4 days, water is not gone up in face, field, to promote that rice shoot is taken root, fills with deep water, use weed killer herbicide after 4-5 days, keeps water layer 5-7 days, puts shallow water in field in time afterwards, promote to tiller; Middle and later periods timely dry field, controls ineffective tillering, promotes root system development, and adhere to dry wet, intermittent irrigation, remain that Tian Tuchen is real, mud does not fall into pin, strengthens improving activity of root system and capacity for the resistance to lodging; When seedling number close to required spike number 80% time, draining dry field, will keep shoaling layer during grouting, results before within 5-7 days, cut off the water supply;

4) weeding: after rice shoot all vertical seedling, mix loam with weed killer herbicides such as Machete, A Luojin, bensulfuron-methyls and spread fertilizer over the fields, and the water layer 5-7 days keeping field 3cm thick, water can not flood the seedling heart, notices that dispenser can not be too early, in order to avoid hinder seedling, also should not be excessively slow, otherwise can herbicidal effect be affected;

5) rational application of fertilizer: when rice shoot is all upright, executed tillering fertilizer in conjunction with pouring water, per hectare executes urea 80-100kg, executes urea 50-70kg make ear manuer at the jointing initial stage, after Qi Sui, per hectare can spray potassium dihydrogen phosphate 3kg, to reach blue or green bar yellow maturity, not early ageing, non-lodging.

The invention has the beneficial effects as follows: the inventive method is reasonable, easy to operate, it is convenient to implement, reduce the burden of peasant, can increase the selenium content of bud seedling, application the inventive method, rice shoot root system number is many, root hair is many, root volume is large, there is not sprout term disease, seedling packing is good, seedling of cannot not turning green slowly after rice transplanting, directly takes root and survives, start effective tiller in advance, can increasing both production and income be realized.
