Abstract
The invention belongs to the technical field of crop cultivation management and more specifically relates to a weed prevention and control method of organic vegetable cultivation. The weed prevention and control method comprises continuous rotary tillage and weeding, close panting to prevent weeds or intertillage and ridge plowing for weeding. In the continuing interval, field biogas slurry spraying and rotary tillage are repeated 2-5 times; weeds are removed to the utmost extent in the continuing interval, and then planting cultivation in such a manner of close panting to prevent weeds or intertillage and ridge plowing for weeding is selected according to the growth cycle of crops. The weed prevention and control method of organic vegetable cultivation has the advantages that the weed prevention and control technology having higher benefit is developed on the basis of inheriting the traditional weeding technology, and therefore, the labor cost is reduced and the economic benefit of organic planting is improved.
Description
Technical field
The invention belongs to Crop Planting Management Agriculture Expert technical field, more specifically relate to a kind of weeds control method being suitable for vegetable-cultivating organic.
Background technology
Farmland weed is a part in agricultural ecosystem, and carries out violent competition between crop, directly or indirectly affects agricultural production.Main harm comprises: fight for moisture, nutrient, illumination and space with crops, the insect pest that spreads disease, reduction seed output and quality.The Crop damage caused is only second to damage by disease and insect.
In recent years, along with growth in the living standard, the requirement of people to vegetables exceedes grain gradually, and its economic worth is also far above grain.Because vegetable species is various, planting patterns is various, and the rotation of crops is fast, and cropping index is high, and soil, water and fertilizer condition are good, and field of vegetables is suitable for multiple weed growth.Endangering heavy weeds to vegetable fields has more than 100 to plant, and wherein preponderates in all kinds of field of vegetables with weeds such as kitchen garden, barnyard grass, lamb's-quarters, recessed head amaranth, eleusine indica, green foxtail, cyperus irias.
Can not use any chemical herbicide in vegetables organic farming, the herbicidal methods of employing mostly is traditional weeding technique, comprises intertill and clean tillage, crop rotation, deep ploughing and intensive cultivation, artificial weeding etc.These herbicidal methods grasp simple to operate, easy and to vegetables and environmentally friendly, there is the irreplaceable advantage of other weeding technique, but the length that expends time in, labour drop into many, along with rural laborer shifts to city, rural laborer's labor cost rises steadily, and according to investigations, is engaged in labour's labor cost of general farming activities in 120 yuan/people/sky, this adds input cost undoubtedly, reduces vegetable growing benefit.
In view of above reason, on the basis of inheriting tradition weeding technique, develop new, that benefit is higher weeds control technology and there is important production practices meaning.
Summary of the invention
In view of this, the invention provides a kind of weeds control method being suitable for vegetables organic farming, on the basis of inheriting tradition weeding technique, the weeds control technology that development benefit is higher, reduces labour cost, promotes the economic benefit of organic grow.
Technical problem to be solved by this invention is achieved by the following technical programs:
A weeds control method for vegetable-cultivating organic, comprises and connects a batch rotary tillage weeding, the anti-grass of dense planting or cultivation and banking weeding.
Further, the described batch rotary tillage weeding concrete operations that connect comprise:
1), after preceding crop results, in order to accelerate, preceding crop is rotten and minimizing weed seed is solid, and carry out timely rotary tillage to residual crops and weeds, rotary tillage severity control is at 15-40cm;
2) after first time rotary tillage, spray natural pond liquid, increase soil fertility and promote growing of weed seed in soil, when weeds grow 2-7cm, carry out the timely rotary tillage of second time;
3) connecing in batch neutral gear, " field sprays natural pond liquid-rotary tillage " 2-5 time is repeated.
Further, the anti-grass of described dense planting be applicable to sow or migrate to results be less than 50 days be incorporated as thing soon, planting density be the 1.5-3 of this kind of crop general planting doubly.
Further, described cultivation and banking weeding be applicable to sow or migrate to results be greater than 50 days be incorporated as thing slowly, during cultivation, line space is increased to the 1.5-3 of this kind of crop general planting doubly, one shallow ridges is dug during plantation, when inter-row weed needs to remove, topdress in conjunction with field, ditch gradation is in the ranks dug to desired depth.
Further, described shallow ridges ditch depth is 3-7cm, divides and digs for 2-5 time to desired depth 20-30cm.
The present invention, relative to prior art, has following advantage and beneficial effect:
The present invention connects batch rotary tillage weeding obviously can reduce in front stubble soil the harm again of carrying grass-seed and causing, and sprays natural pond liquid, and repeatedly rotary tillage after first time rotary tillage, promotes the germination and growth of grass-seed in soil, weeds a garden to greatest extent connecing a batch neutral gear phase; The anti-grass roots of dense planting is according to vegetable variety feature, and the rational close planted when planting, improves the competitive ability of vegetables and weeds, increase the yield per unit area simultaneously.Cultivation and banking weeding is according to the crop characteristic of length in vegetative period, and appropriateness increases line space, in the process of topdressing, carry out weeding in enormous quantities simultaneously, effectively reduces artificial weeding number of times and labour's input.Connect a batch rotary tillage weeding and can reduce weeds generating capacity 60%, the anti-grass of dense planting can reduce weeds generating capacity more than 50%, and increase yield of vegetables more than 50%, cultivation and banking weeding can reduce artificial uprooting weed 4 times, saves labour 12/mu.Traditional weeding system combines with modern weeding theory by the present invention, and anti-grass is effective, has fabulous application prospect in organic production.
