Key technical points of conservation tillage
Conservation tillage is an advanced agricultural technology that is sown by no-tillage or less tillage under the condition that the surface is covered with crop straw or stubble.
The main purposes of conservation tillage are: first, to improve soil structure, improve soil fertility, increase soil water storage and water conservation capacity, enhance soil drought resistance and increase grain yield; The second is to enhance soil erosion resistance, reduce soil wind erosion and water erosion, and protect the ecological environment. Third, reduce operation links, reduce production costs and improve the economic benefits of agricultural production. The basic characteristics of conservation tillage are that the land is not plowed and the surface is covered with straw or stubble.
According to the principle of conservation tillage technology and the practice of developing conservation tillage in different regions, the key technical points and recommended technical models of six suitable regions are put forward. In practical application, we can integrate with other technologies according to the regional characteristics and follow the technical points, and innovate the technical mode suitable for this region.
One,Ridge farming area in northeast China(including paddy fields in Northeast China)
The main problems in this region are: seasonal drought; Long-term ploughing forms the plough bottom, which makes the plough layer shallow; Decline of soil fertility, land degradation, etc.
(A) the technical points of key links
oneLeisure period
Minimize ground breaking, preferably no tillage; Straw mulching can store more rain and snow and reduce water evaporation. If stubble mulching is adopted, high stubble should be left as far as possible; If subsoiling is carried out in the leisure period, a moisture collector is required to reduce moisture evaporation.
2Sowing date
Encourage direct sowing by no-tillage method. In the case of large amount of straw, uneven straw coverage and uneven soil, in order to improve the sowing quality, appropriate less tillage method can be adopted to reduce the straw coverage on the surface or level the land.
threeField management period
According to the local production practice, thinning seedlings, topdressing, pest control and so on. In order to break the bottom of the plow, reduce soil hardening and store rainwater, subsoiling can be carried out without affecting crop growth.
fourHarvest period
Straw can be crushed and returned to the field at the same time of harvesting, and the crushed straw should be evenly scattered.
(B) recommended technology model
oneLess tillage, stubble cleaning and sowing in the original ridge.Straw or stubble should be covered for overwintering, and sowing should be done in the original ridge in spring, and the amount of ground breaking should be reduced as much as possible to reduce water evaporation and operation energy consumption.
2No-tillage sowing with staggered rows of original ridges.Straw or stubble cover the winter, and when sowing in spring, stagger the original stubble for no-tillage sowing.
threeNo-tillage sowing in the original ridge.Straw crushing or stubble mulching overwintering, and direct no-tillage sowing on the original ridge in spring.
fourLess tillage and planting in paddy fields in Northeast China.In autumn, no-tillage stubble overwinters in paddy field. Before transplanting rice, strip rotary tiller is used to carry out strip rotary tillage and fertilization suppression operation. After soaking in the field, rice seedlings are transplanted in rotary tillage belt.
Second,Farming-pastoral ecotone along the Great Wall
The main problems in this region are: severe drought in spring affects timely sowing, and it is easy to cause seed exposure and seedling emergence, and the seedling rate is low; The wind erosion of farmland is serious, and the desertification trend is intensifying.
(A) the technical points of key links
oneLeisure period
No tillage. Cover with as much straw as possible to store more rain and snow and reduce water evaporation; If stubble mulching is adopted, high stubble should be left as far as possible.
2Sowing date
Encourage direct sowing by no-tillage method. In the case of extreme drought, measures such as sitting in water and sowing can be adopted.
threeField management period
According to the local production practice, thinning seedlings, topdressing, pest control and so on.
fourHarvest period
Straw can be crushed and returned to the field at the same time of harvesting, and the crushed straw should be evenly scattered. In windy areas, the crushed straw can be fixed in an appropriate way.
(B) recommended technology model
oneNo-tillage and mulching sowing.Straw or stubble should be left to cover the winter, and no-tillage should be used for sowing in spring, so as to avoid the original stubble as far as possible, so as to improve the coverage rate of ground straw after sowing, ensure the smooth germination of seeds and protect the growth of seedlings.
2No-tillage and sitting in water for sowing.Straw or stubble mulch overwintering, in the case of extreme drought in spring, soil moisture can not guarantee sowing, with water supplement technology, no-tillage and sitting water sowing.
threeStrip no-tillage and mulching sowing.In order to solve the problems of large amount of soil for potato planting and exposed farmland prone to wind erosion, strip no-tillage mulching sowing technology can be adopted. The technical point is that potatoes are planted in a conventional way, and other crops are sown in straw or stubble covered fields with no-tillage fertilization seeder.
fourNo-tillage and replanting of forage.It is mainly suitable for grassland improvement and no-tillage planting forage grass in abandoned land and abandoned land. In rainy season, no-tillage replanting (sowing) forage grass with no-tillage replanting machine is adopted to increase the surface coverage, reduce water evaporation and promote grassland vegetation restoration.

Summer: after wheat harvest, the straw is crushed and scattered evenly, covering the ground; Or after the straws are picked up, stubble is left for covering.
Autumn: after the corn is harvested, the whole straw is covered or the straw is crushed, scattered and evenly covered; If silage is used for harvesting, stubble can be left to cover.
2Sowing date
Summer sowing crops should be sown in no-tillage mode, and in the case of large amount of straw, less tillage mode can be used.
For autumn sowing crops, in a large number of corn stalk covered areas, less tillage or no tillage can be used to sow; If in silage corn field, no-tillage sowing should be adopted.
