Abstract

The invention provides a planting technology for killing and restraining root-knot nematodes without pesticide. The planting technology mainly comprises the following steps that according to the fact that the growth and propagation characteristics of the root-knot nematodes are that the root-knot nematodes live in group and cannot resist high temperature, boiling water is pouring on the portion with root-knot nematode polypides so that adult root-knot nematodes and root-knot nematode eggs can be killed instantly; according to the plant mutual promotion principle, nematode-restraining and nematode-expelling plants including garlic, green onion, fragrant-flowered garlic and the like are planted in an intercropping mode, antibiotic secreted by root systems, remained in soil, of the plants through germ microbial decomposition are utilized, so that the growth and the propagation of the root-knot nematodes are effectively controlled, and inundation of the root-knot nematodes is avoided. By the adoption of the planting technology for killing and restraining root-knot nematodes, the ecological environment is improved fundamentally, the quality of agricultural products is improved, the cost investment is reduced, the labor intensity is relieved, and the economic benefits and the social benefits are improved.

Description

Eliminate and the planting technology that suppresses root-knot nematode

Technical field

The invention belongs to agricultural planting control root-knot nematode technical field, particularly a kind of without agricultural chemicals, eliminate and the planting technology that suppresses root-knot nematode.

Background technology

At present, aspect agricultural planting control root-knot nematode, be mainly to adopt: 1 pesticide control, 2 soil removal and replacement controls, 3 soilless culture controls, 4 vexed canopy controls, 5 water logging controls, 6 crop rotation plantation controls, 7 microbial controls, 8 electricity controls wait and prevent and treat method.

1. pesticide control, to drop into agricultural chemicals (being much violated high-toxic pesticide) in soil generally can only to kill the adult of root-knot nematode not high to the ovum effect of root-knot nematode, not only cost is high and the heavy damage ecotope, makes agricultural product quality have serious potential safety hazard, and control efficiency is poor.2. soil removal and replacement control, be first crop plant residue and the planting soil of removing with worm, and so not only labour intensity is large, recruitment is many, and fertile soil can not be utilized, and the later stage secondary is also very fast.3. soilless culture control, cost is high, the product yield that yields poorly is not good enough, does not reach the ecologic planting standard.4. vexed canopy control, be the leisure season that utilizes crops for rotation, must be high temperature season, and airtight booth utilizes hot weather that the temperature deinsectization is provided, this method not only the time long, weak effect, also very large to the booth material damage.5. water logging control, be subjected to condition and kind plant binding hours long.6. crop rotation plantation control, be the plant restriction root-knot nematode growth reproduction of planting in turn anti-root-knot nematode, this long income that has a strong impact on of method cycle of preventing and treating.7. microbial control, take effect slow, to the large problem of insect density, can't solve.8. electricity control, the high potential safety hazard that exists of cumbersome cost, it is poorer that other prevent and treat method.At present the great difficult problem of worldwide agricultural planting aspect the preventing and treating of root-knot nematode, is badly in need of a kind of efficiently, the planting technology of economy, environmental protection.

Summary of the invention

The purpose of this invention is to provide a kind of particularly without " eliminating and the planting technology that suppresses root-knot nematode " the present invention of agricultural chemicals be mainly eliminate 1. high temperature, high humidity moment the root-knot nematode technology be according to root-knot nematode be grown in surface layer soil 3-9 centimeters plant primary roots in a large number gregarious, self-reproduction is fast, the characteristics of diffusion slow (main outer power diffusion), be chosen in while pulling out the first crop crop moment high temperature to be infused, to be watered in strain body that root-knot nematode harm is arranged and place, cave with boiling water to kill adult and the ovum of root-knot nematode.2. interplant the crop that (intercropping) garlic, green onion, leek etc. have walking quickly and keeping away and suppress the root-knot nematode growth reproduction, thereby its principle is to secrete the plain growth and breeding of effectively controlling root-knot nematode of desinsection of inhibition root-knot nematode growth reproduction after utilizing the crop roots such as garlic, green onion, leek to be decomposed by bacterial micro-organism, reduce insect density, reduce harm.Plant the crops such as garlic, green onion, leek under fruit tree and can well reduce the harm of root-knot nematode.3. earth's surface utilizes the steam rapid steaming to kill the method for control after covering the insulation such as plastic sheeting for farm use.

The advantage of the technology of the present invention is simple, easily promote the use of, do not need to drop into special equipment, there is no economic input, intercropping garlic, green onion, leek are can also create unnecessary income according to the yield and quality that plant interpromoting relation in five elements principle can not affect the essentialspecies plant, are optimal a kind of economy in agricultural planting, environmental protection, eliminate and the planting technology that suppresses root-knot nematode efficiently.

Claims

1. the planting technology that presses down root-knot nematode of going out is mainly:

1. utilize high temperature, high humidity to infuse, water adult and the ovum of killing root-knot nematode.

2. intercropping garlic, green onion, leek etc. utilize bacterial micro-organism to decompose the growth reproduction of residual root system secretion desinsection element inhibition root-knot nematode, reduce insect density, eliminate the harm of root-knot nematode to crop.

3. according to claim 1. the described principle that high temperature, high humidity infuse, water the adult of killing root-knot nematode and ovum is used 3. plastic sheeting for farm uses etc. to cover airtight input steam high temperature and is eliminated adult and the ovum of root-knot nematode.
