Problems solved by technology

Compared with field soil and nutrient soil as the seedling-raising substrate, the seedling-raising substrate using crop straw as the main raw material avoids damage to the paddy field topsoil and solves the problem of raw materials, but the problems of labor cost and environmental pollution are prominent, and it is difficult to popularize and apply

Abstract

The invention discloses soil dressing plug seedling raising matrix for rice, and a seedling raising method thereof, and belongs to the technical field of seedling raising soil dressing matrix of plant seedling plugs. The soil dressing plug seedling raising matrix for the rice is characterized by comprising pulp, a bonding agent, a water-retaining agent, and fertilizer; each plug of soil dressing plug seedling raising matrix comprises 100.0 to 1,000.0g of pulp, 0.1 to 2.0g of bonding agent and 2.0 to 20.0g of water-retaining agent, and 0.5 to 5.0g of nitrogen, 0.2 to 3.0g of phosphorous, and 0.1 to 1.5g of potassium in the fertilizer. The soil dressing plug seedling raising matrix for the rice comprises the pulp and the water-retaining agent, has the advantages of water and fertilizer retaining, heat preservation and ventilation, simple preparation process, light weight of finished product and the like, and is suitable for plugging and seedling raising of a rice transplanter; the quality of seedlings raised by the soil dressing matrix is superior to that of seedlings raised by the conventional nutritional soil; the seedling raising cost is reduced obviously; and a finished seedling plug is very light, and the load and labor intensity of the rice transplanter can be reduced obviously.

Description

technical field [0001] The invention belongs to the technical field of soil matrix for cultivating seedlings of crops, and specifically relates to a substrate for seedling raising of rice seedling tray and a seedling raising method thereof. technical background [0002] Traditional rice machine-transplanted seedlings are mainly based on field soil or nutrient soil. The specifications of the general seedling-raising should be plastic trays with a length of 58 cm, a width of 28 cm, and a height of 2 cm. With such a seedling tray, the average amount of field soil or The nutrient soil is about 80 kg. Based on the area of ​​200,000 mu of machine-transplanted rice in a certain area, 133 mu of fertile land is needed as a soil source for machine-transplanted seedlings every year, resulting in a serious loss of surface mellow soil. At the same time, machine-transplanted seedlings and seedlings are mainly cooperatives with professional services. The area of ​​machine-transplanted see...
