Abstract

The invention discloses a centralized ploughing and burying returning method of rice and wheat straw. The method includes the steps of rice and wheat straw centralized arrangement, rice and wheat straw deep ploughing and returning to field, soil shallow ploughing and leveling, rice and wheat sowing and planting, field management and the like. According to the method, root layer soil of rice and wheat can have high fertility, tiller strengthening, early sprouting and high-yield promotion are facilitated, mechanical operation of management links like straw arrangement and centralized ploughing and burying, sowing (planting), field plant protection and fertilizer application can be achieved, an empty zone is especially reserved for a mechanical operation way, and full-process mechanical production of rice and wheat after farmland scale operation is better facilitated.

Description

Rice and wheat straw is concentrated to plough and is buried also field method

Technical field

The present invention relates to a kind of rice and wheat straw concentrates cultivated burying to go back field method.

Background technology

For a long time, the high yield constantly pursuing crop is the unremitting pursue of a lot of agricultural science worker, and the high yield of crop of how increasing soil fertility, realize, needs the continuous research and probe of research of agricultural science person; Conventional cultivation method needs further to improve.

Summary of the invention

The object of the present invention is to provide a kind ofly to increase soil fertility, the rice and wheat straw that realizes high crop yield concentrates to plough and buries also field method.

Technical solution of the present invention is:

A kind of rice and wheat straw is concentrated to plough and is buried also field method, it is characterized in that: comprise the following steps:

(1) rice and wheat straw is concentrated and is unclogged and readjusted: rice straw or wheat stalk are pulverized when results paddy rice or wheat, and by 300cm ~ 400 cm width of being often separated by, stalk is concentrated and unclogs and readjusts in about 50cm wide cut, make field be the distribution of 300cm ~ 400 cm open country band, the alternate formula of 50cm stalk band;

(2) rice and wheat straw deep ploughing also field: plough deeply at stalk band with trench plow, ploughing depth >=30cm; Rice straw or Wheat Straw are carried out plough buried;

(3) to plough shallowly soil flattening: shallow-layer is carried out to soil and ploughs rake, plough the rake degree of depth at 8-12cm, revolved or shallow rake tillage control measure leveling soil by shallow;

(4) rice wheat broadcasts cultivation: by wheat or rice sowing or be planted in 300cm ~ 400 cm wide without stalk district, wheat or rice sowing or after planting, field is the distribution of 300cm ~ 400 cm wheat or rice growth belt, the alternate formula of 50cm sky web; When the plant protection of not overslaugh field or fertilizer machinery walking, concentrate the both sides of cultivated buried strap also can broadcast or plant 1 row wheat or rice at the stalk that 50cm is wide, but empty web is not less than 35cm;

(5) field management: in rice or wheat process of growth, empty web is used for field plant protection, fertilizing management aisle, is convenient to mechanization management; Cut off the water supply in paddy rice and put the field phase, manage out the drainage ditch of rice field of wide 20cm, dark 10cm ~ 15 cm in empty web, the draining being convenient to field Quick drainage dry field and rice maturity is damp proof.

Advantage of the present invention: one is that rice and wheat straw is concentrated to plough and buried also field, be conducive to controlling stalk with germ and worm's ovum to propagate in field and to cause harm; Two is that rice wheat seeds are implanted in and did not deep plough and without the plot of straw-returning, made rice wheat root layer soil have higher fertility, is conducive to strong tiller and early sends out high yield short; Three is that stalk concentrates cultivated also field of burying can significantly reduce mechanical energy consumption, and the rationally rotation year by year of stalk deep ploughing band, can deepen plough horizon, increase soil fertility; Four is can realize stalk unclog and readjust and concentrate the do mechanization operation ploughed and bury, broadcast the management links such as (cultivation), field plant protection and fertilising, and web of leaving a blank especially is in advance used as mechanical work aisle, and after being more conducive to field scale operation, the entire mechanization of rice wheat is produced.

Below in conjunction with embodiment, the invention will be further described.

Embodiment

A kind of rice and wheat straw is concentrated to plough and is buried also field method, comprises the following steps:

(1) rice and wheat straw is concentrated and is unclogged and readjusted: rice straw or wheat stalk are pulverized when results paddy rice or wheat, and by 300cm ~ 400 cm width of being often separated by, stalk is concentrated and unclogs and readjusts in about 50cm wide cut, make field be the distribution of 300cm ~ 400 cm open country band (without improving straw mulching district), 50cm stalk band (stalk concentrates Dui Shi district) alternate formula;

(2) rice and wheat straw deep ploughing also field: plough deeply at stalk band with trench plow, ploughing depth >=30cm; Rice straw or Wheat Straw are carried out plough buried;

(3) to plough shallowly soil flattening: shallow-layer is carried out to soil and ploughs rake, plough the rake degree of depth at 8-12cm, revolved or shallow rake tillage control measure leveling soil by shallow;

(4) rice wheat broadcasts cultivation: by wheat or rice sowing or be planted in 300cm ~ 400 cm wide without stalk district, wheat or rice sowing or after planting, field is the distribution of 300cm ~ 400 cm wheat or rice growth belt, the alternate formula of 50cm sky web; When the plant protection of not overslaugh field or fertilizer machinery walking, concentrate the both sides of cultivated buried strap also can broadcast or plant 1 row wheat or rice at the stalk that 50cm is wide, but empty web is not less than 35cm;

(5) field management: in rice or wheat process of growth, empty web is used for field plant protection, fertilizing management aisle, is convenient to mechanization management; Cut off the water supply in paddy rice and put the field phase, manage out the drainage ditch of rice field of wide 20cm, dark 10cm ~ 15 cm in empty web, the draining being convenient to field Quick drainage dry field and rice maturity is damp proof.
