Problems solved by technology

At the same time, in the double-cropping rice area, the temperature is high during the growth of late rice seedlings, the rice seedlings grow fast, and the height of the seedlings easily exceeds the suitable height for machine-transplanted seedlings, which is inconvenient for machine-transplanted problems. After spraying the growth regulator, the plant height can be effectively controlled

Embodiment 1

[0027] Embodiment 1: the preparation method of rice straw seedling raising matrix, comprises the following steps:

[0028] (1) Rice straw is a material with abundant sources in rice producing areas. When rice is harvested by machine, it is required to harvest the whole grass for transportation. After harvesting (it can be dried in the field if conditions permit), the straw is shaved and transported to the drying yard, where it is exposed to the sun and dried. The rice straw dried in the sun can be crushed with a feed grinder, and the particle size of the crushed particles should be below 2mm.

[0029] (2) Before rice straw stacking and retting fermentation, fertilizers such as nitrogen, phosphorus, potassium compound fertilizer, bio-organic fertilizer or organic-inorganic compound fertilizer were prepared according to the required amount in advance. It is preferable to add 70-80g of pure fertilizer per 100L of substrate. Nitrogen, 40-60g phosphorus pentoxide, 60-80g potassium...

Embodiment 2

[0035] Embodiment 2: as the preparation method of the rice straw seedling raising substrate special for late rice, comprise the following steps:

[0036] (1) Rice straw is a material with abundant sources in rice producing areas. When rice is harvested by machine, it is required to harvest the whole grass for transportation. After harvesting (it can be dried in the field if conditions permit), the straw is shaved and transported to the drying yard, where it is exposed to the sun and dried. The rice straw dried in the sun can be crushed with a feed grinder, and the particle size of the crushed particles should be below 2mm.

[0037] (2) Before rice straw stacking and retting fermentation, fertilizers such as nitrogen, phosphorus, potassium compound fertilizer, bio-organic fertilizer or organic-inorganic compound fertilizer were prepared according to the required amount in advance. It is preferable to add 70-80g of pure fertilizer per 100L of substrate. Nitrogen, 40-60g phospho...

Abstract

Disclosed are a new sprout cultivation matrix by taking straw as rice and a manufacturing method of the matrix. The matrix is composed, by weight, 75 percent to 80 percent of the straw, 20 percent to 25 percent of rice field fine earth, fertilizer and water. The manufacturing method of the matrix comprises the following steps of firstly, drying and smashing the straw, secondly, modulating the fertilizer and blending the matrix, thirdly, performing stack retting and fermentation, and fourthly, performing disinfection treatment. According to the matrix, waste in the rice production is fully recycled, manufacturing and operation are easy and convenient to implement, and the rice seedling quality is good.

Description

technical field [0001] The invention relates to a rice seedling-raising substrate and a preparation method thereof, in particular to a rice machine-transplanted industrialized seedling-raising substrate and a preparation method thereof. Background technique [0002] Most of the southern part of our country is a double-cropping rice area. There are many production links of double-cropping rice and strong seasonality. Among them, the transplanting link requires a lot of labor and is labor-intensive. Vigorously promoting the mechanized rice transplanting technology can effectively compete for farming time and reduce labor intensity. It is an effective measure to improve the efficiency of rice production. At present, the area of ​​machine-transplanted rice in my country is small, and the technical bottleneck encountered in the promotion of machine-transplanted rice seedlings is mainly seedling raising. The quality of rice seedlings is the key to the success of machine-transplant...
