Abstract
The invention provides a high-yield cultivation technology for rice. The technology comprises the following steps of seed preparation, seedling bed preparation, seed soaking and germination acceleration, sowing, weeding, water and fertilizer management, transplantation, rational close planting, topdressing and disease and pest sabotage. According to the technology, per unit area yield of the rice is improved, stress resistance is improved, and high and stable yield of rice cultivation can be achieved.
Description
Technical field
The present invention relates to agricultural planting field, be specifically related to high-yielding rice cultivation technique.
Background technology
Paddy rice is southern staple food crop, and double cropping rice cultivated area more than 4,000,000 mu, accounts for foodstuff planting area more than 90% throughout the year, and paddy always produces 1,800,000 tons, accounts for the more than 92% of grain aggregate.Rice varieties is constantly released the above high yield and high quality kinds of 550 kilograms of per mu yields, 650 kilograms, 700 kilograms, but when spread, average per unit area yield only has 450 kilograms.Main cause is that in current rice cropping, custom adopts the fertilizer practice of " front heavy, hollow, rear benefit ", adds that heavy seeding seedling transplants, and cultivation is basined irrigation in plate field, causes paddy growth rich water gas unbalance, growth of cereal crop seedlings big rise and big fall, and sick worm takes place frequently.
Summary of the invention
The object of the invention is to solve existing technological deficiency, a kind of high-yielding rice cultivation technique is provided, improve rice yield, reach the object of rice cropping stable high yield, raising resistance.
The technical solution adopted in the present invention is: high-yielding rice cultivation technique, comprises the steps:
A, select suitable local plantation, Resistant, anti-fall, tiller strong, fringe is large, ripening rate is high high-quality, high yielding variety seed;
B, select that physical features is smooth, leeward on the sunny side, the deep fertile ripe nonirrigated farmland of soil layer or ground, vegetable garden makes medium for dry breeding of seedling bed ground, meticulous whole ground, accomplishes that soil is in small, broken bits without bulk, manages moisture in the soils by 1.5 meters, 25 centimetres of ditch depths, railway carriage or compartment is high 15 centimetres; Apply by every mu of seedbed 1500-2000 kilogram of the high-quality farmyard manure, the potash fertilizer 5-8 kilogram that fully become thoroughly decomposed and make base fertilizer;
C, seed is tedded to 1-2 days, soak 12 hours with 3% carbendazim liquid again, clear water is eluriated, until that water becomes is clear, then uses the water of 50-60 DEG C by seed preheating, seed is wrapped with wet gunnysack, with straw insulation, temperature remains on 30-35 DEG C, is progressively cooled to 20 DEG C of left and right after rice bud exposes again, spread seed out, refine under field conditions (factors) bud 1 day;
D, both can sow above by 10 DEG C when temperature is stable, seed rice accomplish rare close evenly, every mu of seeding in nursery bed 10-12 kilogram, the epiphragma of after planting puing up a shed.
After e, rice growing, weeding in time, the 2 leaf phases that were seeded into keep seedbed soil moistening, and 2 leaf after dates will be controlled water wet down.
F, execute 5 kilograms, urea every mu of 2 leaf phase, execute urea 7-8 kilogram, potash fertilizer 2-3 kilogram every mu of 4 leaf phase; Carry out hardening in the 4.5-5 leaf phase, prepare transplant, transplant before 3-4 days every mu execute urea 1.5-2 kilogram.
G, turn over plough mu in conjunction with rice field before transplanting and execute organic 1500-2000 kilogram, mu execute general calcium 40-50 kilogram, potash fertilizer 8-10 kilogram in conjunction with harrowing a field and make base fertilizer.
H, determine Transplanting Density, every nest is planted band leaf seedling 1-2 seedling, and duplicate rows bar is planted: large row 0.9-1.0 chi, and little row 0.4-0.5 chi, nest is apart from 0.4-0.5 chi.
I, topdress, sick worm harm.
The invention has the beneficial effects as follows: improve rice yield, improve resistance, reach rice cropping stable high yield.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
