Description
Technical field
The invention belongs to Crop Planting Management Agriculture Expert technical field, be more particularly to a kind of weeds control method being suitable to vegetable-cultivating organic.
Background technology
Farmland weed is that in Agro-ecological System carries out violent competition between ingredient, and crop, directly or indirectly affects agricultural production.Main harm includes: with crops contention moisture, nutrient, illumination and space, the insect pest that spreads disease, reduction yield and quality.The Crop damage caused is only second to pest and disease damage.
In recent years, along with growth in the living standard, people gradually exceed grain to the requirement of vegetable, and its economic worth is also far above grain.Owing to vegetable species is various, planting patterns is various, and the rotation of crops is fast, and multiple crop index is high, and soil, water and fertilizer condition are good, the suitable multiple weed growth of field of vegetables.Have more than 100 to plant the weeds of vegetable fields harm weight, wherein preponderate in all kinds of field of vegetables with weeds such as Herba Portulacae, barnyard grass, Herba chenopodii, concave head Herba Amaranthi tricoloris, Herba Eleusines Indicae, Herba Setariae Viridis, cyperus irias.
Can not use any chemical herbicide in vegetable organic farming, the herbicidal methods of employing mostly is traditional weeding technique, including middle weeding, crop rotation, deep ploughing and intensive cultivation, artificial weeding etc..These herbicidal methods grasp simple to operate, easy and to vegetable and environmentally friendly, there is the irreplaceable advantage of other weeding technique, but expend time length, labour force puts into many, along with rural laborer shifts to city, rural laborer's labor cost rises steadily, and according to investigations, is engaged in labour force's labor cost of general farming activities at 120 yuan/person/day, this adds input cost undoubtedly, reduces vegetable growing benefit.
For these reasons, on the basis of inheriting tradition weeding technique, develop new, benefit 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 to vegetable organic farming, on the basis of inheriting tradition weeding technique, develop benefit higher weeds control technology, reduce labour cost, promote the economic benefit of organic plantation.
The technical problem to be solved is achieved by the following technical programs:
A kind of weeds control method of vegetable-cultivating organic, including connecing 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 include:
1), after preceding crop results, in order to accelerate, preceding crop is rotten and minimizing weed seed is solid, and residual crop and weeds are carried out timely rotary tillage, and rotary tillage severity control is at 15-40cm；
2) after rotary tillage for the first time, spray biogas slurry, increase soil fertility and promote the growth promoter of weed seed in soil, when weeds grow 2-7cm, carry out second time rotary tillage in time；
3) in connecing batch neutral gear, " field sprays biogas slurry rotary tillage " is repeated 2-5 time.
Further, the anti-grass of described dense planting be applicable to sowing or migrate to results less than 50 days be incorporated as thing soon, planting density is 1.5-3 times of this kind of crop general planting.
Further, described cultivation and banking weeding be applicable to sowing or migrate to results more than 50 days be incorporated as thing slowly, during cultivation, line space is increased to 1.5-3 times of this kind of crop general planting, one shallow ridges is dug during plantation, when inter-row weed needs to remove, topdress in conjunction with field, will in the ranks dig to desired depth by several times by ditch.
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 such advantages as and beneficial effect:
The present invention connects batch rotary tillage weeding and can significantly reduce and carry the harm again that grass seed is caused in front stubble soil, sprays biogas slurry, and repeatedly rotary tillage for the first time after rotary tillage, promotes the germination and growth of grass seed in soil, removes weeds to greatest extent connecing a batch neutral gear phase；The anti-grass roots of dense planting, according to vegetable variety feature, the rational close planted when plantation, improves the competitiveness of vegetable and weeds, increases the yield per unit area simultaneously.Cultivation and banking weeding increases line space according to the crop characteristic of trophophase length, appropriateness, carries out high-volume weeding during topdressing simultaneously, effectively reduces artificial weeding number of times and labour force puts into.Connecing 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%, increases yield of vegetables more than 50%, and cultivation and banking weeding can reduce artificial uprooting weed 4 times, saves labour force 12/mu.Tradition weeding system is combined by the present invention with modern weeding theory, and anti-grass is effective, has fabulous application prospect in organic production.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be described in detail.
Embodiment
1
The enforcement time: on May 12nd, 2014 was to June 11.
Implement place: the four seasons share organic farm booth district P28。
Embodiment: using " Fructus Cucurbitae moschatae Brassica campestris L. ssp.chinensis " crop rotation method to carry out, set experimental plot and compare field in enforcement, area is 0.3 mu of ground.The planting form in experimental plot selects " the anti-grass of dense planting ":
1) after Fructus Cucurbitae moschatae results, carrying out rotary tillage for the first time, the degree of depth is about 20cm, then sprays biogas slurry, treats that weeds grow to about 5cm, carries out second time rotary cultivator, and then " field sprays biogas slurry rotary tillage " circulates 3 times.
