A kind of yam seedling raising method

Abstract

The invention relates to a yam seedling cultivation method which specifically comprises the following steps: selecting yam tubers; disinfecting a cutter; cutting the tubers: longitudinally cutting the tubers in a cross shape for twice and transversely cutting into yam sections which are 5-7 cm in length, wherein the average weight of the yam sections is 15-20g; processing the yam sections by using a seed-dressing agent for yam slice sowing propagation; preparing the seedbed; sowing; transplanting after the buds on the yam sections come out from the soil surface by about 3-4 cm. By adoption of the yam seedling cultivation method to breed yam seedlings and produce yam, the unit sowing quantity can be decreased and the cost of the unit sowing can be reduced; at the same time, the special seed-dressing agent is used for processing the yam sections, so that the problem that the yam sections are easy to decay can be effectively solved, the yam sections are early to bud, high in emergence rate, and ordered and consistent in seedling shape, and the rotten rate is reduced to be lower than 0.6%.

Description

technical field [0001] The invention relates to a method for growing seedlings of Chinese yam. Background technique [0002] In the production of yam, two methods are usually used for propagation. One method is to directly sow zero more seeds, plant dragon heads (also known as seeds) and sow yam dunzi to produce yam. Seedling cultivation, producing yam by transplanting yam seedlings. Among the various methods of raising seedlings, the most common method is to raise seedlings with yam. The technical key of using yam Duanzi to raise seedlings is the cutting and cutting surface treatment of yam tubers. The way in the prior art is: first cut the yam seed tuber longitudinally, then cut the yam section horizontally into about 5-7cm long yam section, then dip the yam section into plant ash and sow it on the seedbed for seedling cultivation. This method of raising seedlings is convenient for obtaining materials , simple operation, fast and convenient, etc., but at the same time t...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the deficiencies of the prior art, and aims at providing a method for raising yam seedlings, which improves the tuber cutting method in the traditional seedling raising method, and at the same time uses a special seed dressing agent for cutting yam for seeding and breeding before sowing seedlings The processing of yam slices effectively solves the problems of yam slices that are easy to rot, low emergence rate, large amount of seeds and high cost of seeds
