Description

A kind of ramie hybridizes protector and its application method

Technical field

The present invention relates to agricultural breeding field, protector and its application method are hybridized more particularly to a kind of ramie.

Background technology

Hybridization is the important means of ramie prevalent variety cultivation, and overwhelming majority ramee variety is obtained by hybridizing means at present, As middle ramie 1 (roundleaf green grass or young crops × giantreed blue or green), the miscellaneous ramie in Hunan 1 (circle No. 5 × casting skin of the green grass or young crops root and stem of certain plants), magnificent ramie 3 (Xinyu fiber crops × dilute section bar), Jiangxi ramie 3 (Jiangxi ramie No. 2 × fiber crops) etc..Ramie seed very little, about 800~20,000,000, per kilogram seed, ramie flower is not only non- Often small and very close, titbit growth inside environment is bad, and setting percentage is low, and germination percentage is low, and seed shoot survival percent is extremely low.Ramie During breed breeding, general excellent single root and stem of certain plants using to filial generation carries out vegetative propagation, fixed proterties.It is the seed selection initial stage, past Hybridization is available for toward only 1 root and stem of certain plants or several root and stem of certain plants female parents.Per the root and stem of certain plants or every plant can output germinative seed amount very little, therefore in view of ramie Numb seed vitality is poor, must obtain seed production higher in cross experiment on single root and stem of certain plants, individual plant, just can guarantee that breeding work Smoothly carry out.

Ramie is the herbaceos perennial of cross-pollination, the different flower of monoecism.Its inflorescence is multiple spike indefinite inflorescence, female The raw taper in stem, male flower is spent to blossom on the bottom section position of female flower, inflorescence often male and female flowering and the life of the two intersection.It is male Pollen ejection is come when stamen is opened, in slight smoke-like, wind pollination.On same strain ramie blooming order be：First open Male flower, after open female flower；Middle and lower part male flower is first opened, and top is opened after the top male flower of female flower.Similar to other crops, ramie is miscellaneous Friendship needs to carry out titbit part bagging, isolates pollen, once stigma appearing, it is possible to awarded by the ramie pollen in the air that floats Powder, the purity of cenospecies cannot be guaranteed.Existing isolation pocket, i.e. hybridization bag, are typically made of cured matter paper, brown paper, or Directly use ordinary envelope.These hybridization bags are light tight, poor air permeability, papery bag are frangible, and ramie can be further exacerbated by after bagging The deterioration of titbit growing environment, so as to cause ramie cross-sterility, shaky or solid seed vigor is poor, directly influences miscellaneous Effect is handed over, hybridization failure is even resulted in.And, the not reproducible utilization of these hybridization bags so that production cost is higher.

Ramie is short-day plant, and main product is in China Yangtze river basin.Existing hybridization bag or envelope stock size are smaller, and directly Female connector is on the titbit on ramie top.Wherein larger-size No. 9 envelopes are also only 324mm × 229mm.Kraft paper bag is because of paper Matter is thicker, and excessive sack is also only capable of using less specification because that Ramie Stalk can be caused to bend again very much.Existing hybridization bag It is general stuffy, the lifting surface area of ramie titbit part is increased after bagging, under wind and rain weather, it is easy to because stress is too high Ramie Stalk is caused to bend.Further, since can only select the less hybridization bag to carry out operation, hybridization bag is directly generated to titbit Extruding, deteriorates titbit growing environment.

The ramie male flower florescence is more early than female flower, therefore, to avoid string powder, it is necessary to as early as possible to female flower bagging, treat male flower pollen into After ripe, bagging is removed, recovered again after being hybridized.Pollen after maturation is largely flown away in the air of surrounding, still can be made Into serious string powder phenomenon, crossbreeding effect is influenceed, and increased hybridization operation, improve task difficulty and production cost.

A variety of drawbacks of bagging hybridization are limited to, existing ramie hybridizing method is mainly taken " isolation hybridization method ".Main side Method is to take space of the selection production of hybrid seeds area without other ramie plantings to isolate, or using natural covers such as the woods, buildings, or adopt Isolated with the wattle fence artificially built (Wu be intended to peak brief talk Cross-breeding of Ramie Agriculture in Jiangxi science and technology, 1991,1:17- 18).The specific space length of this method needs and place could be realized, very unfavorable to carrying out hybridization.Meanwhile, this method Multiple male parents are often planted in same isolated area multiple maternal (many father's hybridization), it is difficult to ensure clearly Parent source；Or Person is multiple maternal using 1 male parent, you should pay special attention to maternal emasculation, typically carries out 5~6 times, and workload is very big, it is difficult to list Ramie is effectively managed for strain, and hybridization efficiency is low.

Patent " a kind of robinia pseudoacacia cross-pollination isolation device " (ZL201310218342.6) discloses one kind by support frame and isolation The special hybridization pollination isolating device of bag locust tree dimerous.The effect of its support frame, it is mainly tall and big by locust tree etc. The support force of the solid stalk of trees fixes inflorescence and isolating device, and can strut isolation pocket, forms a space for closing. It includes the insect prevention stratum reticulare and plastic sheeting arranged from the inside to the outside by the isolation pocket that flexible material is made, and sets on a plastic film Have several for breathe freely passage.This device hybridizes for trees, effectively can isolate to local, and uses anti- The layer structure that worm stratum reticulare and plastic sheeting are formed is isolated, and can better conform to the shadow of disorderly air-flow and precipitation in the style of calligraphy Ring.However, Section of Genus Boehmeria herbaceous plant, its straw stiffness is not enough to support the weight of isolating device, and its stalk is typically vertical In ground, hybridization bag can be naturally drooped by gravity, without two effects of support ring and support bar separated from one another, you can shape Into described closing space.Meanwhile, locust tree is locally isolated, the normal life of trees and its most tree bodies is not influenceed Activity, and ramie plant is smaller, and isolation proportion is carried out greatly using the device, will significantly affect its growing environment, such as runs into Dry weather, because air humidity is too low in isolation pocket, can cause blade fast-falling, the decay of ramie vitality, influence hybridization matter Amount.In addition, locust tree is androgyny plant, its hybridization flow is different with ramie, it is impossible to use for reference the device and phase of invention offer The hybridizing method answered.Therefore, the device and its corresponding transformation cannot meet ramie hybridization needs.

The content of the invention
