A kind of ramie hybrid protective gear and using method thereof

Abstract

The invention provides a ramie hybridization protector and a use method thereof. The use method of the ramie hybridization protector comprises the steps of preparation of the ramie hybridization protector, female parent emasculation, head selection of male parents and bagging hybridization. The ramie hybridization protector is formed by assembling a bag body, a support and a bottle body and is characterized in that double-layer cotton yarns and transparent plastic cloth are sewn to form a cylindrical bag body which is breathable in top end, light-transmitting in side face, heat-insulating and moisturized; the cylindrical bag body sleeves the support produced by bamboo poles and an annular part; ramie male parent spicas are cultured by the bottle body holding clear water on the support, so that the aims of effectively isolating single ramies, preventing out crossing, improving a growth environment of ramie female parents, simplifying a hybridization flow, and improving the hybridization efficiency are achieved. According to the ramie hybridization method provided by the invention, pollen outside a hybridization bag can be isolated, ramie stalks are effectively supported, and wind and lodging are prevented; the protector can be repeatedly used, so that the hybridization cost is reduced.

Description

technical field [0001] The invention relates to the field of agricultural breeding, in particular to a ramie hybrid protective gear and a use method thereof. Background technique [0002] Hybridization is an important means of cultivating improved ramie varieties. At present, most ramie varieties are obtained through hybridization methods, such as Zhongzhu No. 1 (Yuanyeqing × Luzhuqing), Xiangzazhu No. 1 (Yuanqing No. ), Huazhu No. 3 (Xinyuma × Xijieba), Ganzhu No. 3 (Ganzhu No. 2 × Jiama), etc. Ramie seeds are very small, about 8 to 20 million seeds per kilogram. Ramie flowers are not only very small, but also very dense. The internal growth environment of the flowers is not good, the seed setting rate is low, the germination rate is low, and the survival rate of seedlings is extremely low. During the breeding process of ramie varieties, it is generally used to asexually reproduce and fix the traits of the excellent single ramie of the hybrid offspring. In the early stage...

Problems solved by technology

At the same time, partial isolation of Robinia pseudoacacia will not affect the normal life activities of the trees and most of them, while ramie plants are small, and the proportion of isolation using this device will be large, which will significantly affect their growth environment. The weather, because the air humidity in the isolation bag is too low, will cause the leaves to fall off quickly, the vitality of ramie will decline, and the quality of hybridization will be affected

In addition, black locust is a hermaphroditic plant, and its hybridization process is different from that of ramie, so it is impossible to learn from the device and corresponding hybridization method provided by this invention

Therefore, this device and its corresponding modification cannot meet the needs of ramie hybridization.
