Problems solved by technology

At present, the edamame soybeans produced in subtropical regions are naturally matured and harvested. They lose their vitality and cannot be kept as seeds. In scientific research, the germination rate of seeds harvested after natural maturation is extremely low.

Embodiment 1

[0014] For the seed cross-selection No. 1 for spring soybean farming in the south of the Yangtze River, fresh soybeans with green pods were picked in advance of live stems on August 1 in the high temperature and rainy season in the middle of the drum before the pods and stems turned yellow. Divide the green pod soybeans into small mesh bags of 1kg / bag, and hang them in the shade to avoid exposure to the sun and rain. Use cool wind and shade drying at 30°C, wind speed 3m / s, blow for 5 days and then threshing, so that the moisture content of soybeans is reduced to 12%. The outer layer of the seeds is specially coated by a seed coating machine. The soybean germ-preserving coating agent consists of 1.0% chitin, 7% Bacillus thuringiensis, 15% natto resin, 0.4% trace elements, 1.6% guar gum and auxiliary materials corn Made from powder. 5BYJ-3.0 type coating machine is used to coat the outer layer of seeds, the ratio of seeds to coating agent is 1:50, the pH is adjusted to 6.0, and...

Embodiment 2

[0016] In the later stage of bulging before the soybean pods and stems turn yellow, fresh green pod soybeans are picked in advance of the live stems. Divide the green pod soybeans into thin layers of 5 cm, and avoid exposure to the sun and rain under shaded pergola conditions. Use cool wind and shade drying at 30°C, wind speed 4m / s, blow for 5 days and then threshing, so that the moisture content of soybeans is reduced to 13%. The outer layer of the seeds is specially coated by a seed coating machine. The soybean germ-preserving coating agent consists of 0.9% chitin, 7% Bacillus thuringiensis, 15% natto resin, 0.6% trace elements, 1.5% guar gum and auxiliary materials corn Made from powder. 5BYJ-3.0 type coating machine is used to coat the outer layer of seeds, the ratio of seeds to coating agent is 1:75, the pH is adjusted to 6.5, and the seed damage rate is less than 0.2%. Take out on March 25, have the effect of preventing pest and keeping germination rate at 94%. The se...

Embodiment 3

[0018] In the middle and late stages of bulging before the pods and stems turn yellow, pick fresh soybeans with green pods in advance. Divide the green pod soybeans into thin layers of 10 cm, and avoid exposure to the sun and rain under shaded pergola conditions. Use cool wind and shade drying at 30°C, wind speed 5m / s, blow for 5 days and then threshing, so that the moisture content of soybeans is reduced to 11%. The outer layer of the seeds is specially coated by a seed coating machine. The soybean germ-preserving coating agent consists of 1.1% chitin, 7% Bacillus thuringiensis, 15% natto resin, 0.5% trace elements, 1.4% guar gum and auxiliary materials corn Made from powder. 5BYJ-3.0 type coating machine is used to coat the outer layer of seeds, the ratio of seeds to coating agent is 1:100, the pH is adjusted to 7.0, and the seed damage rate is less than 0.3%. Take out on March 30, have the effect of preventing pest and keeping germination rate at 96%. The seed bank is st...

Abstract

The soybean seed preparing and preserving method includes picking fresh bean pod to collect seed, drying seed in shady and cool condition, coating seed with soybean coating agent of 25 % concentration and comprising chitin, bacillus thringiensis, natto resin, trace element, guar gum, etc. capable of affecting physiological metabolism, and storing at low temperature condition. The said method can keep soybean seed from the high temperature and rainy condition, prevent and control diseases and pests and raise germination rate.

Description

technical field [0001] The invention relates to a seed production and preservation method of spring edamame, in particular to a seed production and preservation method in subtropical regions, and belongs to the field of plant genetics, breeding and seed production and processing. Background technique [0002] Spring edamame in subtropical regions is a fresh edible vegetable soybean. It is sown in April under open field cultivation conditions without facilities, and harvested from late June to August. After harvesting, the seeds are stored in the next spring. Due to the high temperature and rainy months from June to August in the subtropical region, the soybean protein will quickly denature and cause the seeds to lose their vitality. Therefore, no matter whether it is soybean breeding or the breeding of soybean improved varieties in production, the germination of seeds cannot be guaranteed (Wu Siming (1956) Journal of Zhejiang Agricultural College , Wang Jinling (1970) "Soybe...
