Abstract

Provided is a planting method for preventing and curing strawberry successive cropping obstacles. The planting method comprises the first step of planting strawberry previous crops, such as leguminosae, wheat and rice, carrying out 4d sunlight sterilization and disinfection on the soil in the daytime after the previous crops are harvested, and carrying out 3d ultraviolet lamp disinfection in a greenhouse in rainy days, the second step of preparing continuous cropping preventing fermentation liquor, using pericarpium citri reticulatae viride, immature bitter orange, resurrection lily rhizome and turmeric as a substrate, inoculating trichoderma, carrying out light cultivation for two weeks, obtaining the fermentation liquor to be sprayed to the soil with the spraying amount as 20-30kg/mu, the third step of soaking seeds in biogas slurry, drying the seeds in sunny days, teding the seeds for 1-2 days, carrying out impurity removal, soaking the dried seeds in the biogas slurry for eight hours, washing the seeds with clear water after seed soaking, drying the seeds to prepare for germination accelerating and seeding, the fourth step of carrying out secondary spraying of the continuous cropping preventing fermentation liquor, spraying outside roots, and spraying 25-35kg of the fermentation liquor per mu, wherein the fermentation liquor is diluted by clear water mixed with polyaspartic acid for one time when one strawberry compound leaf is expanded.

Description

The implantation methods of control strawberry continuous cropping obstacle

Technical field

The present invention relates to a kind of cultivated strawberry method, particularly relate to the implantation methods of control strawberry continuous cropping obstacle.

Background technology

Strawberry (Fragaria ananassa Duch) is subjected to continuous cropping obstacle to affect one of very serious crop.Continuous cropping obstacle is the challenge that perplexs for a long time agricultural production, although waning etc., pathogenic soil microorganism, allelopathy, soil nutrient elements can cause the generation of continuous cropping obstacle obstacle, but soil micro-ecosystem is unbalance be continuous cropping obstacle occur basic, this point is generally acknowledged by the researcher; Poly-aspartic-acid (polyasparticacid; English abbreviation PASP) be a kind of amino acid whose polymer, a kind of water-soluble polypeptide, biodegradable, have certain biologically active, its as fertilizer sources synergist, can absorb with enrichment soil in the element favourable to plant growth, can improve the availability of fertilizer.Strengthen crops resistance.

Summary of the invention

Technical problem to be solved by this invention provides a kind of cultivation method of controlling the strawberry continuous cropping obstacle, this method by suppress pathogen infringement in the soil and degraded to the secretion of strawberry root system from poisonous substance matter to improve the anti obstacle to continuous cropping ability of strawberry.

To the invention provides a kind of implantation methods of preventing and treating the strawberry continuous cropping obstacle in order overcoming the above problems, to may further comprise the steps:

The first step: stubble is pulse family, wheat or paddy rice before the plantation strawberry; Soil carries out daylight sterilizing 4d daytime after the front stubble harvesting, can utilize ultraviolet lamp sterilization 3d in case of overcast and rainy in booth;

Second step: the anti-continuous cropping zymotic fluid of preparation: rascal, the dried immature fruit of citron orange, Kaempferia galanga, turmeric as matrix, are inoculated Trichoderma, and 28 ℃ of light cultivated for two weeks, made zymotic fluid, were sprayed to soil, and the sprinkling amount is 20～30kg/ mu.

The 3rd step: natural pond liquid seed soaking: select fine day to bask seeds, ted 1～2 day, then removal of impurities will shine good seed and invade natural pond liquid, soak 8 hours, and seed soaking should clean up seed after finishing with clear water, then dry, in order to vernalization, sowing;

The 4th step: anti-continuous cropping zymotic fluid secondary sprays: adopt the mode of root outer spraying, after strawberry emerged, when a slice compound leaf launched, every mu of clear water that sprays to sneak into poly-aspartic-acid 1.2kg diluted zymotic fluid 25～35kg of 1 times.

Useful effect: use the inventive method by suppress pathogen infringement in the soil and improve the microenvironment of strawberry soil and decompose to the secretion of strawberry root system from poisonous substance matter, not only can control the strawberry continuous cropping obstacle, promote the seed physiology metabolism, and can strengthen disease-resistant, the anti-adversity of strawberry, poly-aspartic-acid has fertilizer synergistic, improved utilization rate of fertilizer, above method synthesis utilization has improved the anti-continuous cropping ability of strawberry in cultivated strawberry.

Embodiment

The invention will be further described below in conjunction with embodiment:

A kind of implantation methods of preventing and treating the strawberry continuous cropping obstacle may further comprise the steps:

The first step: stubble should be pulse family, wheat, paddy rice before the plantation strawberry; Soil carries out the daylight sterilizing daytime after the front stubble harvesting, can utilize ultraviolet lamp sterilization in case of overcast and rainy in booth;

The present invention has confirmed in the continuous cropping obstacle control efficiency that the ground such as the Nanjing six directions, Jiangning carry out, and obviously improves with its survival rate of this method control strawberry continuous cropping obstacle, can effectively overcome the strawberry continuous cropping obstacle.

Claims

1. prevent and treat the implantation methods of strawberry continuous cropping obstacle, it is characterized in that: may further comprise the steps:

Second step: the anti-continuous cropping zymotic fluid of preparation: rascal, the dried immature fruit of citron orange, Kaempferia galanga, turmeric as matrix, are inoculated Trichoderma, and 28 ℃ of light cultivated for two weeks, made zymotic fluid, were sprayed to soil, and the sprinkling amount is 20～30kg/ mu;
