Novel machine seedling transplanting and seedling culture method

Abstract

The invention relates to a novel machine seedling transplanting and seedling culture method. According to the method, during earthworm excretion substrate preparation, earthworm excretion obtained after Taiping No. earthworms eat milk cow excretion is utilized and is subjected to sieving processing, and obtained materials are uniformly mixed with field sieved fine soil according to a proportion being 1:1; the sieved fine soil is used as covering soil; fresh fodder grass straws are spread and paved on the bottom of a seedling culture disc; substrates, spraying water, rice seeds to be seeded and the covering soil are contained in the seedling culture disc, and the seeding is completed. The method provided by the invention overcomes the defects that in the prior art, the fertility continuity cannot be anastomotic with the rice seedling growth requirement and the machine seedling transplanting performance, and the problem of three-leaf and one-core yellowing can be solved through once additional fertilizer application in the one-leaf and one-core period of the rice. The method has the advantages that heat generated by respiration and absorption in the covering and seed root developing process and the seedling field moisture effects are utilized for promoting the fodder grass straws to gradually become thoroughly decomposed, the nutritional requirements are just supplemented when the rice grows to the three-leaf and one-core state, and the goals of forming strong seedlings, increasing the single-planting white root quantity, improving the root system packing performance, increasing the stem thickness and promoting the machine transplanting survival rate improvement and fast living plant green turning are achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a novel machine-transplanted seedling raising method. Background technique [0002] As a modern rice production method, machine transplanting has the characteristics of high operating efficiency, labor and labor saving, and increased production and efficiency. It is the development trend of modern rice planting. At present, the main bottleneck restricting the development of machine-transplanted rice seedlings is the quality of rice seedlings and the performance of machine-transplanted rice seedlings. [0003] Before the present invention, although there were many existing machine-transplanted seedling-raising methods, there were few methods that could meet the requirements of machine-transplanted seedlings, such as strong seedlings, good packing, many white roots, good performance of raising seedlings with soil, and fast greening and survival after pla...

AI Technical Summary

Problems solved by technology

There are many studies on seedling substrates, most of which use decomposed organic matter or the formula combined with inorganic fertilizers. It is difficult to match the sustainability of fertility with the growth needs of rice seedlings and the performance requirements of machine transplantation. Solve the problem of three-leaf one-centered yellowing, which often leads to root development that is difficult to meet the requirements of machine transplanting for packing effect and seedling looseness

This not only increases production costs, but also complicates work procedures and affects production efficiency
