Abstract
The invention discloses a high-yield cultivation method for rice row-expanding thin-planting groups with fore-rotating crop oilseed rape. The steps comprise: (1) selecting a high-quality rice variety, performing thin sowing and culturing multi-tiller healthy seedlings; (2) configuring base fertilizer and tillering fertilizer, the base fertilizer comprising 48-52 kilograms of ammonium bicarbonate used for seedling, 30-35 kilograms of superphosphate, and 4-8 kilograms of potassium chloride, the tillering fertilizer comprising 2-3 kilograms of urea used for seedling, planting in a row-expanding manner, and applying fertilizer; (3) performing shadow water irrigation in an earlier stage of planting, after the seedlings grow to 80%, performing filed draining, performing in fractions, first being light and then heavy, maintaining a field water layer in a rice heading filling period, and after that, performing moistening irrigation at interval, field being wet and dry alternatively, and primarily being wet. The method is advantaged by effectively increasing productive panicles and the total number panicles of in each mu, and increasing maturing rate to a certain extent.
Description
Technical field
The present invention relates to a kind of high yielding culture of rice method, the high-yield cultivating method of the paddy rice Kuo Hang thin planting colony of stubble rape especially.
Background technology
Paddy rice (formal name used at school: Oryzasativa) is the one of draft Oryza, is also the longest main one as grain in Oryza.Annual, gramineous plants, unifacial leaf, property happiness is warm and humid.Spending of rice is very little, and when blooming, main spray can present arch, down all can hold little Hua between 30 to 50 centimetres in end of the branch, and most of self-pollination also bears seeds, and is called spike of rice.The size of general spike of rice in 5 to 12 millimeters long, 2 to 3 mm of thickness.
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 ".Paddy rice institute knot reality and paddy, claim rice, scented rice, rice after paddy (grain) shells.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 wine etc.Paddy rice, except edible, can also be made wine, refine sugar and make the raw material of industry, rice husk, rice straw, can as feed.Mainly the Northeast, the Yangtze river basin, China paddy rice main producing region, Pearl River Delta.Belong to direct economy crop.Still the staple food of 1/3rd mankind in the world.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of high-yield cultivating method of paddy rice Kuo Hang thin planting colony of front stubble rape.
The present invention is achieved through the following technical solutions.
A high-yield cultivating method for the paddy rice Kuo Hang thin planting colony of front stubble rape, step comprises:
(1) select high-grade rice kind, light seeding is cultivated many tillers and is strengthened seedling;
(2) configure base fertilizer and tillering fertilizer, base fertilizer comprises mu and executes carbon ammonium 48-52 kilogram, superphosphate 30-35 kilogram, potassium chloride 4-8 kilogram, and tillering fertilizer comprises mu and executes urea 2-3 kilogram, expands row and plants and applies fertilizer;
(3) cultivation shallow irrigation in early stage, put field after 80% enough seedlings, gradation is carried out, and heavy after first light, Filling stage keeps field water layer, afterwards interval moistening irrigation, alternation of wetting and drying and to wet.
Further, also configure fringe granulated fertilizer, fringe granulated fertilizer comprises mu and executes urea 3.5-5 kilogram, potassium chloride 3-7 kilogram.
Further, configure the insecticide of control two generation rice leaf roller during cultivation, it comprises mu 48% Le Siben missible oil 70-90ml, 90% Cupric sulfate 60-80g, water 50-70 kilogram.
Further, the insecticide of configuration control rice fulgorid and banded sclerotial blight during cultivation, it comprises the mould clear 100-200ml of mu 12.5% line, Rynaxypyr 10-12ml, Buprofezin 70-90g, water 50-60 kilogram.
Beneficial effect of the present invention:
Effectively can increase the effective fringe of mu and total grain panicle number, and certain amplitude improves ripening rate, and method is comparatively practical, reduces labour intensity, the cultivation for paddy rice provides new thinking.
