Problems solved by technology

[0003] For the problems existing in the prior art, the purpose of the present invention is to provide a method for rice substrate semi-water seedling raising, which solves the shortcomings of water seedling raising and dry seedling raising, and at the same time, solves the technical problems of industrialized dry seedling raising. The growth and management of rice seedlings in the south, the seedlings cultivated by this method meet the requirements of mechanized transplanting, such as high seedling density, uniformity, strong seedlings, well-coiled roots, light weight, and convenient transportation.

Embodiment 1

[0044] A method for semi-aqueous seedling raising of rice substrate, the method is to use a mud-like seedling bed equipped with modern agricultural rainproof, heat preservation or sunshade facilities, use a seedling tray to pack the substrate to raise seedlings, keep the substrate moist, and then place the seedling tray in the mud Shaped seedling-raising seedling bed, the seedling-raising mode that does not irrigate seedling seedling bed surface in the whole seedling raising process; Its concrete method comprises the following steps:

[0045] A. Preparation of seedling bed:

[0046] Irrigate and permeate the seedling bed with a rotary tiller once, soak it for 2 days and then rotate it again, add 25kg of 45% balanced compound fertilizer per mu (that is, per 667 square meters) and rake the slurry for 2 days; keep the seedling bed It is in a state of mud and no water; the seedling bed is flat, and drainage and irrigation facilities are prepared around it; according to every 3m wi...

Embodiment 2

[0067] The method of rice substrate semi-water seedling raising of the present embodiment is basically the same as embodiment 1, and the difference is that, B, the selection of substrate: the selection adopts self-contained substrate; described self-provided substrate is calculated by volume fraction Yellow clay: shriveled rice husk: peat soil = 4:5:1 deployment, add 1kg of organic fertilizer with 70% organic matter per cubic meter of main material, and 50g of seedling strengthening agent; the nitrogen content of the organic fertilizer is ≤5%; Cultivation field needs to prepare 70-100 liters of substrate.

Embodiment 3

[0069] The method of rice substrate semi-water seedling raising of the present embodiment is basically the same as embodiment 1, and the difference is that, B, the selection of substrate: the selection adopts self-contained substrate; described self-provided substrate is calculated by volume fraction Yellow clay: shriveled chaff: peat soil = 4:5:1 deployment, adding 1.3kg of organic fertilizer with 70% organic matter per cubic meter of main material, and 70g of seedling strengthening agent; the nitrogen content of the organic fertilizer is ≤5%; It is necessary to prepare 70-100 liters of substrate for a large field of cultivation.

Abstract

The invention discloses a paddy rice matrix half-water sprout cultivation method, and the method comprises the steps of using a muddy sprout cultivation seedbed that has a modern agriculture rainproof, insulating or sunshade facility; employing a sprout cultivation plated matrix for sprout cultivation; maintaining the matrix moistening; disposing the sprout cultivation plate in the muddy sprout cultivation seedbed; and keeping no irrigation in the sprout cultivation seedbed surface in the whole sprout cultivation process. The detail method comprises the steps of A preparing the sprout cultivation seedbed; B matching the matrix; C preparing a sprout cultivation apparatus and related apparatuses; F packaging the matrix in plates, disinfecting and sowing in a seeder streamline; G accelerating germination; H cultivating a matrix half-water sprout cultivation seedbed; and I managing cultivation. The method solves the problems of both water sprout cultivation and dry sprout cultivation; at the same time, the technical problems of sprout cultivation in a factory is solved; growth and management in southern paddy rice sprout cultivation is benefited; mechanical transplanting requirement like high and uniform seedling density, of the cultivated seedling, vigorous sprout, good root junction, light weight and convenient transportation are realized.

Description

technical field [0001] The invention relates to the technical field of rice seedling raising, in particular to a method for semi-water seedling raising of rice substrate. Background technique [0002] my country has almost all adopted water seedling raising in the history of rice cultivation in thousands of years, which is very prone to serious stuffy seedlings, sprouting, and rotten seedlings. In the 1990s, dry seedling raising was introduced and popularized, which solved the problem of rotten seeds and seedlings, and dry seedling raising has become the current seedling raising method. However, under high temperature conditions, dry seedlings will grow excessively (prosperously) or burn seedlings. With the promotion and popularization of seedling throwing technology and machine transplanting technology, the excessive growth of rice seedlings is not conducive to the rooting and rejuvenation of Honda, and the dry seedling cultivation has gone to another extreme, which cannot...
