Problems solved by technology

[0005] At present, the commonly used sowing method is mainly to use seedling trays and seedling bags to sow seeds. The quality of the seedlings obtained is weak, and it needs to be transplanted twice, which affects the quality of the seedlings and the cost is high.

Embodiment

[0024] A light and simplified method for raising seedlings of sweet potato seeds, which uses a series of technical means such as manual cutting of seed coats, direct sowing in soil, small sheds, micro-spraying devices, sunshade nets and insect-proof nets, etc., to solve the problem of hard seed coats of sweet potato seeds. The problem of water absorption and germination, low emergence rate, weak seedlings and poor quality can be solved, and the production of sweet potato seed seedlings can be light and simplified, and the unity of high germination rate, high emergence rate and high strong seedling rate can be realized.

[0025] Specifically, it includes the following steps:

[0026] (1) Seed preparation: The seedlings with Jishu 26 as female parent and Jishu 21 as female parent that were harvested in 2016 and obtained by group hybridization and laissez-faire pollination were selected. Rinse with clean water first to remove impurities and some seeds with low specific gravity, c...

Abstract

The invention relates to a light simplified seedling raising method for sweet potato true seeds. A diagonal nail clipper is used for cutting seed coats, a series of technical means of soil seedling raising, small plastic arch shed establishing, micro spray device laying, sunshade net covering, pest control net covering and the like are used, the problems that sweet potato true seed coats hard anddifficultly permeate and absorb oxygen, germination rate is low, seedling rate is low, weak seedlings is more and the quality is poor are solved, and the unification of sweet potato true seed seedlingraising light simplification, the high germination rate, the high emergence rate and the strong seedling rate is achieved. By adopting the method, compared with other methods, the operation is simpler and safer, and the method is lower in cost and higher in seedling germination rate and emergence rate, is more capable of obtaining strong seedlings, and provides protection for breeding of novel sweet potato varieties.

Description

technical field [0001] The invention relates to a light and simplified method for raising sweet potato seedlings, and specifically belongs to the technical field of sweet potato seedling raising. Background technique [0002] Sweet potato (Ipomoea Latatas Lam.) is an important grain, industrial raw material, feed and new energy crop, and it is also one of the best health foods praised both at home and abroad. Sweet potato has high yield, stable yield, strong stress resistance, and wide adaptability. Because of its advantages of less input, more output, and lower risk, it has become increasingly prominent in the fields of health food, fuel ethanol, and starch processing. Therefore, there is an increasing demand for new sweet potato varieties. [0003] At present, in the production of new sweet potato varieties in our country, the main method is to use hybrid combinations to obtain sweet potato seeds, and plant seedlings to screen out lines with excellent traits, so as to obt...
