Abstract
The invention relates to a protected land farming method in arid region, falling into the technical field of farmland protection, to solve the problems of spring drought, difficult seedling emergence, lean soil, low crop yield, etc. The protected land farming method comprises the steps of deep plowing after crop harvest in autumn of the current year, applying fertilizer in soil according to type of to-be-planted crops in the next year, covering straw on the fertilized soil at amount of 15,000 Kg/hectare, mulching film according to type of to-be-planted crops in spring of the next year, keeping the straws between two films, and planting according to conventional method. The protected land farming method utilizes waste straw to retain moisture in arid land soil, prevent water evaporation, fertilize soil, and prevent water/soil loss.
Description
Technical field
The invention belongs to the cultivated land protection technical field, be specifically related to protection ground, a kind of arid area expedient of tillage.
Background technology
China dryland farming district accounts for 52% of China's territory total area, is distributed in 16 provinces and regions, the north, and about 3,300 ten thousand hectares of the gross area accounts for 1/3 of total area under cultivation.Drought-hit area, the north generally adopt at present with mouldboard plow turn over, the tillage method of the exposed leisure in the face of land; Make earth receive serious water erosion wind erosion; Cause that northern area soil depletion, river are muddy, sandstorm is rampant, valuable cultivated land resource constantly receives damage, and is restricting agricultural sustainable development.
Summary of the invention
The present invention is primarily aimed at arid in nonirrigated farmland spring, the insemination and emergence difficulty, and soil depletion, crop yield are low, and water and soil loss, the river is muddy, sandstorm is rampant problem, and protection ground, a kind of arid area expedient of tillage is provided.
The present invention addresses the above problem the technical scheme of taking to be:
Protection ground, a kind of arid area expedient of tillage: after the crops results in autumn,, in soil, apply fertilizer then according to the kind of planting crops the coming year in conjunction with deep ploughing; Ratio according to 15000 kilograms of per hectares covers the soil of executing overfertilization with stalk then, and to the kind covering with plastic film of 1 year spring according to the plantation crops, stalk is retained between two width of cloth mulch films; Plant according to conventional method when waiting to plant, behind 1 year crop harvesting, clear up residual film; The deep placement chemical fertilizer in the position of plastic mulching; According to the position that the ratio of 7500 kilograms of per hectares covered with the stalk covering with plastic film, in the 3rd year early spring, the stalk that covered in 1 year is rotten basically; Cover row with 1 year stalk of plastic mulching, get final product according to the conventional method plantation when waiting to plant.
The present invention adopts technique scheme; Utilize wastes straw to protect the moisture of dryland soil; Prevent the evaporation of moisture, fertilizing soil is avoided water and soil loss; Prevented muddy, the rampant pollution on the environment that causes of sandstorm in river simultaneously, impelled the nonirrigated farmland to develop towards the direction of sustainable development.
Embodiment
Protection ground, a kind of arid area expedient of tillage is then after the crops results in autumn, in conjunction with deep ploughing; Kind according to planting crops the coming year is applied fertilizer in soil, and the ratio according to 15000 kilograms of per hectares covers the soil of executing overfertilization with stalk then, to the kind covering with plastic film of 1 year spring according to the plantation crops; Stalk is retained between two width of cloth mulch films, plants according to conventional method when waiting to plant, behind 1 year crop harvesting; Clear up residual film, the deep placement chemical fertilizer in the position of plastic mulching, the position that covered with the stalk covering with plastic film according to the ratio of 7500 kilograms of per hectares; The 3rd year early spring; The stalk that covered in 1 year is rotten basically, covers row with 1 year stalk of plastic mulching, gets final product according to the conventional method plantation when waiting to plant.Autumn, deep ploughing fertilizer was with operation in 1 year.Reach like this to protect and hold soil moisture, fertilizing soil is avoided the effect of water and soil loss.
