A kind of cotton seedling raising and transplanting method

Abstract

The invention provides a cotton seedling nursing and transplanting method comprising steps of manufacturing a seed bed, processing seeds, sowing, managing the seed bed and transplating. During the seed bed manufacturing step, a seed bed is leveled and partions are paved on the seed bed; 6 to 9cm thick loosening soil is paved on the seed bed; the soil is sprayed by water with bactericide for future use; during the seed processing step, seeds are dries, soaked and then mixed with accelerating germination agent before sowing; during the seed sowing step, the bed soil is adjusted to enable the water content of the bed soil to be 75 to 85%, and then seeds are evenly sowed one by one; then the seeds are covered by disinfection soil or bed soil; during the seed bed management step, the temperature of the seed bed is controlled to be 20 to 30 DEG C and humidity 70 to 85%; insect pest diseases are timely prevented; during the transplanting step, before transplantation, growth regulator is applied to the seed bed and the seed bed is watered to be humid; and within 24 hours, seed fetching, transplantation and root fixing water application work are finished. By the use of the method, damage to roots can be prevented during transplantation; the method requires low cost; survival rate can reach as high as 95% after plantation; only 2 to 3 days are required for seed rejuvenation period; the seeds can early bud; the transplantation process is simple, easy, safe and reliable; and by the use of the cotton seedling nursing and transplanting method, time and labor use can be reduced and the method is suitable for large field production.

Description

Technical field [0001] The invention relates to the technical field of crop cultivation and breeding, in particular to a method for raising and transplanting cotton seedlings. Background technique [0002] There are five main methods for transplanting cotton seedlings: [0003] The first method is field soil / seed bed nursery, which is the traditional method of transplanting a variety of crops. Taproot plants, such as cotton, with an absolute dominant taproot, are difficult to grow after the root system is damaged when the seedlings are taken from the soil. Since the 1980s, some people have studied and promoted the application of techniques to prevent dead and dead seedlings from transplanting plants. The survival rate of field soil nursery transplanting is greatly improved and the slow seedling period is shortened. Soil seedling cultivation is not restricted by conditions, easy to operate and easy to master, so it is still the most important method for crop seedling cultivation. ...

AI Technical Summary

Problems solved by technology

Including pot type, box type, and plug type, some use soil, and some use soilless substrates for cultivation. The advantage of this method is that it is convenient to take out the seedlings and transplant them with a relatively complete root system. The problem is that large containers are conducive to Cultivate strong seedlings, but the seedlings take up a lot of space, and it is difficult to transport and transplant. Small containers are conducive to management and transplanting, but the growth space of seedlings is small, and it is difficult to grow strong seedlings. After planting, weak seedlings have a long seedling period and are easy to stiff The dead seedlings will affect the growth, yield and quality of the field, and the cost of raising seedlings is also higher than that of soil seedbeds

[0008] To sum up, most of the traditional cotton seedling transplanting methods are easy to cause damage to the root system, and a large number of dead seedlings and stiff seedlings occur. The use of containers or nutrient pots has problems such as more labor, low production efficiency, and high cost of seedling cultivation.
