Abstract

The invention provides a novel paddy rice early direct seeding and cultivation method which includes the following steps of paddy selection, variety selection, rush seeding, rotary tillage and seeding, timely shallow water irrigation and timely drainage to keep soil moist and free of accumulated water, chemical weeding, timely fertilizer supplement, paddy sunning at a proper time, timely water supplement and disease prevention the same as that of common paddies. The method saves water, effort and labor, increases the yield, and is environmentally friendly, few in plant diseases and insect pests, high in setting rate, short in growth period, simple and convenient to operate and beneficial to large-scale production.

Description

A kind of paddy rice is live novel cultivation method early

Technical field

The present invention relates generally to a kind of cultivation method, relates in particular to early live novel cultivation method of a kind of paddy rice.

Background technology

Rice direct-seeding is exactly not carry out seedling, transplanting and a kind of planting type of directly seed being sowed to land for growing field crops.Large area rice direct-seeding can be saved a large amount of labours, alleviates the seasonal nervous contradiction of labour, to realizing lightness, specialization, the scale of Rice Production, has great significance, and has wide promotion prospect.But compare with transplanting rice, direct seading rice exists that difficult full stand, crop smothering are heavy, the easy Three Difficult Issues that lodge.Therefore, on producing, should be specifically noted that and grasp technical measures such as " full stand are early sent out, the anti-evil of weeding, the anti-early ageing of getting fat, healthy and strong cultivation lodging-prevention ".

Summary of the invention

The object of the invention is just to provide early live novel cultivation method of a kind of paddy rice.

The present invention is achieved by the following technical solutions:

Paddy rice is a live novel cultivation method early, comprises the following steps:

(1) rice field is selected: field is smooth, soil fertility is sufficient, and field ditch is supporting, has source of irrigation water;

(2) kind is selected: semilate rice or precocious late rice are main;

(3) assault is robbed and is broadcast: preferably select cloudy weather can keep 3-5 to become a fine day, according to weather forecast, select job date;

(4) rotary tillage and sowing: use urea 10-20 kilogram for every mu before rotary tillage, calcium phosphate 30-40 kilogram, seed will be soaked seed with seed soaking spirit and bird repellent, and the time is 24-36 hour, and kind of a 5-7kg for every mu, japonica rice broadcasts and with hand tractor, covers seed afterwards;

(5) go up shallow irrigation in time, draining in time, keeps soil damp without ponding;

(6) second day starts chemical weed control for the first time, and every mu is used the spirit of 170-200ml36% floods and droughts, adds 10% wetting powder bensulfuron-methyl 20-30g;

(7) according to grass, select mutually professional weed killer herbicide, notice that field keeps shoaling layer, will manually pull out above the average age for marriage Su Shengcao;

(8) timely supplementary fertilizer: in the 4 leaf phases of paddy rice, use 45-50kg biological organic fertilizer for every mu for the first time, for the second time in the paddy rice shooting stage, use urea 28-30kg for every mu;

Described biological organic fertilizer is comprised of the raw material of following weight parts:

Oil foot 20-30, corrupt vegetables 10-20, swill 10-15, weathered coal 4-6, cotton stalk powder 6-8, bamboo charcoal powder 2-3, eucalyptus oil 1-2, peanut shell 2-3, little paulin 2-3, luffa vine 2-3, grape leaf 2-3, humic acid 2-3, distiller's dried grain 3-4, the people's animal wastes 100-120 of flying;

Above-mentioned oil foot, corrupt vegetables, swill, peanut shell, the little paulin, luffa vine, grape leaf of flying are mixed, add the water of compound weight 20-30%, the salt of 1-2%, at 80-90 ℃, be heated to water dry, discharging is cooling, mixes with each raw material of residue, stirs, normal temperature is stacked 15-20 hour, granulation;

(9) put field in good time: for the first time after seedling to 4 leaf phases roasting field by force, with growth-promoting root, in the rice tillering later stage, start to put field for the second time, keep the edge of a field damp later.

(10) moisturizing in time, at rice milking stage in earlier stage, keeps field to have water, until milk ripe stage starts really to put field;

(11) disease control, with general paddy rice control.

Advantage of the present invention is:

Method water saving of the present invention, saving of labor, laborsaving, volume increase, environmental protection, damage by disease and insect is light, ripening rate is high, breeding time is short, easy and simple to handle, be conducive to develop large-scale production.
