Oilseed rape blanket-shaped nursery special matrix and its preparation method

Abstract

The invention discloses an oilseed rape blanket-shaped nursery special matrix and its preparation method. The matrix comprises mushroom residue treated by fermentation and decomposition, acid-sludge,manioc waste mixed fermenting material and coco coir, carbon bran, plant ash and turf, vermiculite, and perlite. The matrix is prepared from, by volume, 20-30 parts of fermenting material, 10-20 partsof coco coir, 5-10 parts of turf, 5-10 parts of vermiculite, 5-10 parts of perlite, and 3-5 parts of carbon bran or plant ash. Besides, the matrix is further added with 0.3-0.5% by total weight of composite fertilizer and 0.1-0.3% of synergist. The preparation method of the matrix includes raw material selection and processing, material fermentation, matching and mixing, fertilizer blending, testing and adjustment of physicochemical indexes, quantitative packing, and other steps. The matrix is high in nutrition content, stable in structure, good in blanket forming effect and has a certain fiber; the matrix is very suitable for cultivate oilseed rape blanket-shaped nursery; compared with seedbed soil nursery, the seed nursery rate is improved by about 10%; after sprouting, the surviving rate is improved by about 15%; the tidiness of the height of seedling is improved by 15-20%' the difference of the average tidiness of 10 disks of seedlings is reduced by 15-20%.

Description

technical field [0001] The invention relates to a rapeseed seedling raising substrate and a manufacturing method thereof, in particular to a rape blanket-shaped seedling raising substrate and a manufacturing method thereof, which belong to the field of agricultural technology. Background technique [0002] Rapeseed is one of the main crop varieties planted in winter in rural areas of our country. Traditional rapeseed cultivation requires manual seedling cultivation and transplanting, which is labor-intensive and time-consuming, and is not conducive to mechanized operation. It has become a bottleneck restricting the development of rapeseed production in my country. The mechanical transplanting technology of blanket-shaped rapeseed seedlings jointly developed by Yangzhou University and Nanjing Agricultural Mechanization Research Institute of the Ministry of Agriculture uses plastic plugs to cultivate blanket-shaped rapeseed seedlings, and then quickly transplants them with a r...

AI Technical Summary

Problems solved by technology

However, in the actual seedling raising process of rapeseed blanket seedlings, the rapeseed seedling bed soil has a large soil specificity, and the grown rapeseed sheet has problems such as heavy weight, easy looseness, difficulty in blanketing, and difficult transportation; , the nutrients contained are also different, and need to be adapted to local conditions, which is difficult to control; third, the length and thickness of plant fibers are high, and the use of crop straw to produce plant fibers is difficult in actual operation, difficult to grasp the operation process, and it is not easy to standardize on a large scale Production

[0004] For example, using ordinary rice seedling-raising substrate and vegetable seedling-raising substrate to grow rapeseed blanket seedlings, it is difficult to cultivate high-quality rapeseed blanket seedlings because the nutritional ingredients, physical and chemical properties and physical structure cannot meet the requirements of rapeseed seedlings.
