Abstract

The invention discloses a straw complete returning and wheat seeding method, comprising the steps of: seeding wheat in a field before harvest of paddy, then when the wheat is grown for a certain length, the paddy is harvested, crushed and retuned to ditches so achieve the effect of completely returning to the field for utilization; According to the straw complete returning and wheat seeding method, the problem that fall seeding of the wheat is delayed due to harvest of the paddy is overcome, and the problem of low straw returning and utilization ratio is also overcome, straw returning is beneficial to suppressing growth of weeds in the field, quantity of the weeds in the field after the straw has been returned is reduced, acre yield is improved for 30-60kg, significant economic value is brought to agricultural production, and strong practicability and promotional value are provided.

Description

A kind of total straw also field and wheat cultivation method

Technical field

The present invention relates to soil melioration and crop cultivating technology, especially relate to a kind of total straw also field and wheat cultivation method.

Background technology

At present, in the autumn planting time of crops, the sowing major part of wheat is the method adopting mechanical stubble-cleaning or the sowing of plate field after rice harves, the method result in the postponement of wheat cultivation time on the one hand, wheat is broadcast owing to will rob in field on the other hand after results paddy rice, straw after rice harves is treated as a great problem, the processing mode of peasant household is mostly for abandoning to contour furrow canal or burning of setting fire, also the peasant household had stays some separately to do it and uses, only cover after wheat cultivation with a small amount of straw, not only waste good organic resource, but also pollute environment, straw availability is lower.

Summary of the invention

Goal of the invention: existing in the problem that the harvest time wheat cultivation time is postponed and after rice harves, straw availability is low in order to solve in prior art, the present invention proposes one and overcome wheat autumn sowing delay, total straw also field and the wheat cultivation method that straw incorporation rate is low.

Technical scheme: to achieve these objectives, the present invention takes following technical scheme: a kind of total straw is field and wheat cultivation method also, comprises the steps:

(1) 7-10d before the paddy rice harvesting phase, in field, every mu of sowing wheat seed 12-14kg, spreads fertilizer over the fields 45% composite fertilizer 30-40kg;

(2) wheat emerge 1-1.5cm time, with the combine harvesting paddy rice of band straw crushing function;

(3) after gathering in paddy rice, even for the cutted straw in pulverized field spreading is covered field;

(4) with ditching machine excavation furrow ditch, ditch spacing 150-200cm; Excavate three traverse furrows altogether, described traverse furrow lays respectively at two, field and centre position; Ditch soil uniform spreading is sprinkling upon on straw.

More preferred, in described step (2), the pulverizing length of straw is 3-8cm.。

More preferred, traverse furrow furrow width 15-20cm, ditch depth 15-25cm described in described step (4).

Beneficial effect: a kind of total straw provided by the invention is field and wheat cultivation method also, namely in field, the sowing of wheat is carried out before rice harves, then when wheat emerges certain length, paddy rice is carried out gathering in the value pulverized rear also field of also ditching and utilize to reach total crop return, the inventive method had both overcome to gather in paddy rice thus the problem causing wheat autumn sowing partially slow, also solve the problem that straw incorporation availability is on the low side, straw incorporation is conducive to containing that the life of weeds in wheatland exists, in wheatland also behind field, weeds quantity reduces, per mu yield improves 30-60kg, obvious economic worth is brought to agricultural production, there is very strong practicality and promotional value.

Embodiment

Embodiment 1:

7d before paddy rice harvest, in field, every mu is broadcasted sowing wheat seed 12kg, spreads fertilizer over the fields 45% composite fertilizer 30kg; When wheat emerges 1cm, with the combine harvesting paddy rice of band straw crushing function, Rice Powder is broken into the cutted straw of 3cm, be sprinkling upon in wheatland by cutted straw uniform spreadings all for field after harvesting paddy rice, then with ditching machine excavation furrow ditch, ditch spacing is 150cm, separately excavate three traverse furrows respectively at two, field and centre position, furrow width 15cm, ditch depth 15cm, evenly to shed in field on cutted straw by the ditch soil spade dug out; Postmenstruation observes, every mu of total stem tiller 29.6 ten thousand, and average every square meter 3 strain of weeds in field amount, results core produces, every per mu yield 340 kilograms.

Embodiment 2:

10d before paddy rice harvest, in field, every mu is broadcasted sowing wheat seed 14kg, spreads fertilizer over the fields 45% composite fertilizer 40kg; When wheat emerges 1.5cm, with the combine harvesting paddy rice of band straw crushing function, Rice Powder is broken into the cutted straw of 8cm, be sprinkling upon in wheatland by cutted straw uniform spreadings all for field after harvesting paddy rice, then with ditching machine excavation furrow ditch, ditch spacing is 200cm, separately excavate three traverse furrows respectively at two, field and centre position, furrow width 20cm, ditch depth 20cm, evenly to shed in field on cutted straw by the ditch soil spade dug out; Postmenstruation observes, every mu of total stem tiller 30.2 ten thousand, and average every square meter 3 strain of weeds in field amount, results core produces, every per mu yield 360 kilograms.

Use a kind of total straw of the present invention also field and wheat cultivation method and common straw incorporation and wheat cultivation method carry out Experimental Comparison, data are as shown in table 1:

?	Embodiment 1	Embodiment 2	Commonsense method
				Every mu of total stem tiller	29.6 ten thousand	30.2 ten thousand	26.8 ten thousand
Weeds in field/m ²	3 strains	3 strains	16 strains
				Every per mu yield	340kg	360kg	286kg

Table 1 field observation Data Comparison

As can be seen from Table 1, use a kind of total straw of the present invention also field and wheat cultivation method comparatively compared with commonsense method, every mu of total stem tiller adds 10.4%-12.7%, every square meter weeds in field decreases 81%, every per mu yield adds 18.9%-25.9%, obvious economic worth is brought to agricultural production, there is very strong practicality and promotional value.

It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
