Preparation and application of insecticide-fertilizer-solution-soaked base fabric used for rice seedling raising with machine-transplanting hard-plate

Abstract

The invention discloses preparation and application of insecticide-fertilizer-solution-soaked base fabric used for rice seedling raising with a machine-transplanting hard-plate, belonging to the technical field of rice seedling raising. The preparation and application comprise the following process and steps: (1) preparation of bast-fiber base fabric used for rice seedling raising; (2) preparation of an insecticide-fertilizer solution; (3) soaking treatment of the base fabric used for rice seedling raising; (4) application of the soaked base fabric; etc. The preparation and application for the insecticide-fertilizer-solution-soaked base fabric used for rice seedling raising provided by the invention overcomes the problems that difficulty in uniform mixing of borrowed soil, a seedling-strengthening agent and fertilizer affects the growth of rice seedlings and the speed and quality of mechanical transplanting and that the undersoil, the seedling-strengthening agent and the fertilizer are lost from the bottom holes in the hard-plate. According to the invention, the intertwisting power of root systems of rice seedlings is increased by 30%; the application amounts of rice-seedling soil and rice seeds are respectively reduced by 30%; labor is reduced by more than 50%, and the labor intensity is greatly reduced; each base fabric costs only about RMB 0.15 yuan; thus, the base fabric has the characteristics of low cost for rice seedling raising, good quality of rice seedlings, good quality of mechanical transplanting, and high yield.

Description

Technical field [0001] The invention relates to the technical field of rice seedling raising, in particular to a seedling raising device and method for machine-transplanted rice. technical background [0002] With the development of agricultural modernization and mechanization, the requirements for the quality of machine-transplanted rice seedlings are getting higher and higher. At present, the most widely used method of machine-transplanted rice seedlings in the production of rice seedlings is the method of raising seedlings from the hard disk. However, this traditional method mainly has the following problems: if the amount of sowing is large, the quality of seedlings will be poor and the elasticity of seedling age will be small; if the amount of sowing is small, the carpet formation will be poor, the roots of the seedlings will be severely damaged during machine transplantation, and the rate of missed transplantation will be high. The number of seedlings is uneven, and the gr...

Problems solved by technology

But this traditional method mainly has the following problems: if the sowing amount is large, the quality of the seedlings is poor, and the elasticity of seedling age is small; The number of seedlings is uneven, and greening is slow; in addition, due to the inconsistent source of guest soil, it is difficult to control the quality of the seedlings, and the cost is also high. It is easy to disperse the seedlings in rainy days, and it is not resistant to transportation. Moreover, this method can be used directly in the seedling tray with a bottom hole. Adding subsoil, adding fertilizer, etc. will easily cause loss

[0003] 1. It is necessary to mix a large amount of foreign soil or substrate with a small amount or even a small amount of seedling strengthening agent or compound fertilizer. Due to the difference in quality and density between them, it is a labor-intensive task to achieve uniformity. It is a goal that is difficult to achieve, and a slight unevenness can easily lead to uneven growth of seedlings, which in turn affects the overall growth of seedlings and the quality of machine-transplanted plants;

[0004] Two, the bottom of the existing seedling-raising hard disk is all provided with a bottom hole, on the one hand, the bottom hole is to cause the loss of subsoil, seedling strengthening agent or compound fertilizer, etc. added to the hard disk after each watering; The loss also leads to the deterioration of the root system's binding force, easy to loose seedlings, and intolerance to transportation, which in turn affects the quality and speed of planting slots and machine transplanting from the seedling tray;

[0005] 3. Generally, when the early rice seedlings are raised, the ground temperature of the soil in the seedling field is low, and it is easy to pass through the small hole at the bottom of the seedling tray to cause the growth of the seedling tray and affect the growth of the seedlings, and it is easy to be infected by pathogens.
