Method for promoting cucumber growth in continuous cropping field by employing microbial organic fertilizer

Abstract

The invention relates to a method for promoting cucumber growth in a continuous cropping field by employing a microbial organic fertilizer. The method comprises the following steps: (1) screening varieties, namely selecting high-quality cucumber variety which is wide in cultivated area, good in prematurity and strong in growth potential; (2) determining the concentration of an organic fertilizer, namely carrying out serial dilution on a dongshengbao (Chinese character) liquid organic fertilizer, determining the concentration of the liquid organic fertilizer to be 5*10<4>ppm according to the requirements of the cucumber on EC and pH of soil; (3) accelerating germination of cucumber, namely carrying out hot water treatment of cucumber seeds, and seeding after germinating; (4) applying an organic fertilizer, enclosing soil of the continuous cropping field in a greenhouse into 16 flowerpots for pot culture, fertilizing the microbial organic fertilizer with the concentration of 5*10<4>ppm into the flowerpot as a base fertilizer a week before field planting of cucumber seedlings; (5) transplanting the cucumber seedlings, when the cucumber seedlings grow into 4-5 leaves, transplanting the cucumber seedlings into 19cm*20cm of flowerpot; and (6) managing after transplanting, carrying out conventional management on the potted cucumber after transplanting, and ensuring cucumber growth at a preference temperature, wherein the temperature is 20-25 DEG C in daytime and the temperature is 15-20 DEG C at night. The method for promoting cucumber growth in the continuous cropping field by employing the microbial organic fertilizer aims at improving the physical and chemical properties of the soil in the continuous cropping field, promoting cucumber growth and lowering the morbidity grade of the cucumber.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for promoting the growth of continuous cropping cucumbers by utilizing microbial organic fertilizers. Background technique [0002] Dongshengbao liquid organic fertilizer is a kind of natural microbial fermentation principle, through the degradation of microorganisms, the organic waste (such as kitchen waste) in people's daily life is aerobically decomposed by microorganisms on protein and starch, etc. Anaerobic fermentation and degradation, the "organic soil active liquid" with amino acid as the main component produced can not only provide comprehensive nutrition for crops, but also increase and renew soil organic matter, improve soil physical and chemical properties and biological activity. [0003] cucumber( Cucumis sativus Linn ) is one of the most widely cultivated vegetables in my country, and has a cultivation history of more than 2,000 year...

Problems solved by technology

[0005] The object of the present invention provides a kind of method that utilizes microbial organic fertilizer to promote the growth of continuous cropping cucumbers, aiming at the high cost and easy to cause problems in traditional methods of promoting continuous cropping cucumber growth such as using soil physical and chemical disinfection methods, rational crop rotation, and selecting disease-resistant varieties. The problem of secondary pollution and long cycle provides a method of using microbial organic fertilizer as base fertilizer to improve the physical and chemical properties of continuous cropping soil, so as to solve the problems of continuous cropping cucumber yield and quality decline, and increase of pests and diseases. To overcome cucumber continuous cropping obstacles And provide scientific basis for the application of microbial organic fertilizer
