Abstract

The invention discloses a paddy early-planting cultivation method, and belongs to the field of crop cultivation patterns. The paddy early-planting cultivation method is of great importance to solving the problems that seeding is inappropriate, fertilizer application is not reasonable and irrigation is not in place, so that the purpose for guaranteeing high yield is achieved. The paddy early-planting cultivation method includes the steps of timely seeding, timely slinging planting, quantitative seedling controlling, accurate fertilizer application, guaranteeing of high yield, shallow-wet irrigation, root enhancing and tiller promoting. The timely seeding can ensure timely slinging planting. By the aid of timely slinging planting and quantitative seedling controlling, the quality of slinging seedlings can be guaranteed. Accurate fertilizer application can promote large panicles, delay senescence and achieve the functions of root cultivating and leaf preserving. Shallow-wet irrigation can enhance roots and promote tillers, root activity is enhanced, and ventilation and transmitting can be promoted.

Description

Paddy rice is early made cultivation method

Technical field

The present invention relates to arviculture mode field, specifically a kind of paddy rice is early made cultivation method.

 

Background technology

Paddy rice is one of staple crops of China, along with the continuous increase of China's population, the improvement of rice cultivating technique has been become to a urgent demand.From ancient times to the present, China does not have the rice cropping mode of standard, and sowing out of style is all the factor of restriction rice high yield with applying fertilizer unreasonable.

 

Summary of the invention

The purpose of this invention is to provide a kind ofly tally with the national condition, paddy rice that the agriculture feelings require early makes cultivation method.

To achieve these goals, the present invention adopts following technical scheme:

A kind of paddy rice is early made cultivation method, and the method comprises the following steps:

(1) begin sowing in good time:

1 ~ 2 kilogram of every mu of rice field sowing quantity, March 1 finished kind during March 5;

(2) throw and plant in good time, the quantitative seedling:

The rice transplanting leaf age is 4 ~ 4.5 leaves, and the length of time rice seedlings grow is 25 days, throws cultivation while being chosen in fine day or cloudy calm weather, and there are 3 ~ 4 stem tiller seedlings in every cave, and every mu reaches 1.8 ~ 1.9 ten thousand clumps, guarantees Basic Seedling 7 ~ 80,000 clump;

(3) accurately fertilising, guarantee high yield:

While using base manure, mu is executed 25 kilograms of Nitrogen, Phosphorus and Potassium; After planting, paddy rice within 5 ~ 6 days, executes tillering fertilizer, 25 kilograms of 7.5 kilograms, urea or ternary compound fertilizers, 5 kilograms, potassium chloride; Ear manuer was used in the ear differentiation second phase, and mu is executed 10 kilograms, potassium chloride, 5 kilograms, urea; Paddy rice has the two-stage grouting phenomenon, and the later stage will be emphasized granulated fertilizer and top dressing, delays senility, and reaches the effect of supporting Gen Baoye, and granulated fertilizer is seen Miao Bushi in 7 ~ 8 days after ear manuer is executed, if the blade flavescence just imposes, otherwise does not execute; Respectively spray 0.2 ~ 0.3 kg/acre of potassium dihydrogen phosphate at cut phase and full heading time, guarantee that paddy rice needs fertile requirement;

(4) shallow wet irrigation, the short tiller of strong root:

The rice transplanting period of seedling establishment keeps the water layer of 2.5 ~ 3.5cm highland barley alive, within after rice transplanting 7 days, irrigates shallow water in conjunction with executing tillering fertilizer, falls to doing afterwards open field 2 ~ 3 days, loop, keep moistening, make soil in the oxygen enrichment state, the short tiller of strong root, strengthen improving activity of root system, when stem tiller number reaches every mu 17 ~ 190,000, start 3 ~ 5 times and gently put field, every mu of the highest seedling number is controlled at 26 ~ 270,000, promote ventilation and penetrating light, nourished and grew and prosperous will heavily put field, make the percentage of earbearing tiller reach 70% ~ 100%; During to booting stage, adopt Dry-wet alternate irrigation, shallow water booting, coordinate the requirement of root system to aqueous vapor, until ripe.

Beneficial effect of the present invention:

The present invention, to cultivating strong seedling, guarantees the rice transplanting quality, and there is great role quantitative seedling aspect; Aspect fertilising, accomplish accurate fertilising, promote large fringe, support Gen Baoye, delay senility, finally can guarantee high yield.
