Abstract
The invention discloses a method for preventing disease and protecting fruit for mulberry cross pollination. The method comprises the following steps: utilizing a sheepskin paper bag (commonly known as parchment) to bag after the winter bud of the female mulberry sprouts and before the female flower extends; opening the bag and quickly pollinating after the female flower pillar extends and shows the white part; closing the bag opening again, thereby preventing the interference on the pollination caused by the foreign genetic gene (foreign pollen) flowing from air and ensuring the purity of the pollination; preventing mulberry sclerotium disease pathogen from infecting the female flower and fruit of the mulberry; forming the young fruit after the bagged mulberry branch is completely pollinated for more than two times and the mulberry flower withers away, taking off the paper bag and bagging by using a nylon net bag, thereby preventing the damage to the mulberry caused by worms, birds and rats, increasing the ventilating property and the water permeability, reducing the fruit abscission and boosting the normal growth and development of the mulberry. The exchanged sheepskin paper bag and the nylon net bag can be reused. The method provided by the invention has the characteristics of simple operation, raw material-saving property, high pollination purity, capability of effectively preventing mulberry sclerotium disease, reduction of fruit abscission, high yield, high benefit, and the like.
Description
Technical field
The invention belongs to mulberry tree breed breeding technique field, particularly relate to a kind of method of mulberry tree hybridization pollination diseases prevention phylactocarp.
Background technology
Mulberry tree is dioecism, and its breed breeding adopts artificial hybridization to pollinate mostly.During hybridization pollination, generally first select economic characters excellent and the Parent of flower synchronization, paper bag (the template on cover when female flower is just bloomed, be commonly called as parchment) intercept the external gene (foreign pollen) of drift in air to the interference of hybridization, guarantee the purity of hybridizing; The paper bag that male flower is same on anther dehiscence protheca, prepares to collect pollen and uses.Be generally collect pollen noon before that day, in morning next day, open paper bag, with writing brush, pollen is awarded out on the column cap of female flower parent, and then recover paper bag; Repeat to pollinate 2-3 time, bagging is ripe to sorosis always afterwards, receives fruit, and washing fruit and obtain seed, is first-filial generation seed.
Tradition bagging method whole process does not change bag, there is following several respects defect:
<1> sorosis growing period is as strong wind weather, paper bag is easy to be blown brokenly, once paper bag is damaged, fail to glue in time and mend or change, mellow fruit may be caused to land, reduce and receive fruit amount, in addition, sorosis also may be eaten up by bird worm, thus greatly reduces receipts fruit amount;
<2> was as continuous several days rainy weathers, and have little time to receive fruit, the sorosis dropped in paper bag can rot because of paper bag poor air permeability, affects the germination rate of mulberry kind;
<3> paper bag gas permeability, light transmission are poor, differ greatly with natural environment, and these factors can have influence on quality and the quantity of first-filial generation seed.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method of mulberry tree hybridization pollination diseases prevention phylactocarp, to reduce prematurity shedding, improves and receives fruit amount and percentage of seedgermination.
For solving the problems of the technologies described above, the present invention by the following technical solutions: the method for mulberry tree hybridization pollination diseases prevention phylactocarp, after all mulberry branchs of bagging have all awarded powder, paper bag has been taken off and has changed nylon net bag into.
The method of above-mentioned mulberry tree hybridization pollination diseases prevention phylactocarp, until the mulberry branch of bagging all pollinate twice and column wither, form young fruit after paper bag taken off change nylon net bag into.
The method of above-mentioned mulberry tree hybridization pollination diseases prevention phylactocarp, comprises the following steps:
The parent that <1> selection traits is excellent, female parent started to overlap paper bag in the early flowering season, and male parent is at anther dehiscence protheca paper bag;
With writing brush, pollen is awarded on the column cap of female flower after <2> collects pollen, then recover paper bag;
<3> until the mulberry branch of bagging all pollinate twice and column wither, form young fruit after paper bag taken off change nylon net bag into, and tighten sack;
<4>, when there is a small amount of atropurpureus shedding at nylon net bag sack place, can start sorosis of gathering.
Paper bag specification is long × wide is 80cm-100cm × 15cm-20cm, and nylon net bag specification is long × wide is 80cm-100cm × 30cm-40cm.
For Problems existing in traditional mulberry tree hybridization pollination method, inventor in conjunction with the advantage of paper bag and nylon net bag, until the mulberry branch of bagging all pollinate twice and column wither, form young fruit after paper bag taken off change nylon net bag into.So, the external gene (foreign pollen) that can intercept drift in air, to the interference of hybridization, guarantee the purity of hybridizing; Also intercept the female flowers and fruits of diseases of mulberry fruits Pathogen Infection mulberry, young fruit can be allowed again to grow under access expansion environment; Meanwhile, the defect of traditional pollinating method is avoided.Than conventional method, this method is ventilative, printing opacity is good, makes mulberry tree after pollination completes, can grow fast, and normal growth is grown, and can reduce fruit drop, improves first-filial generation sowing rate and percentage of seedgermination.
Wherein, change bag period and need hold proper, too early paper bag can not be changed into mesh bag, too early have the female flower opened late on a small quantity and may receive other pollen and cause first-filial generation seed impure, too lately change bag then sowing rate and percentage of seedgermination improve DeGrain.Therefore, the best period of changing bag is that young fruit is when just being formed.In addition, the paper bag of replacing because of service time not long, loss percentage is little, and can dry rear preservation use again in the coming year, nylon net bag is also reusable, thus reduces production cost.
Embodiment
Embodiment
In January, 2013, in mulberry tree maternal plant garden, select 40, the branch that growing way is basically identical, package with paper bag.Wherein 20 adopt conventional method, and whole process does not change bag; Other 20 adopt new method of the present invention, first overlap paper bag, wait when just forming young fruit and change paper bag into nylon net bag.
Wherein, new method concrete operation step is as follows:
The parent that <1> selection traits is excellent, female parent started to overlap paper bag (specification: long × wide is 80cm-100cm × 15cm-20cm) in the early flowering season, and male parent is at anther dehiscence protheca paper bag;
With writing brush, pollen is awarded on the column cap of female flower after <2> collects pollen, then recover paper bag;
<3> until the mulberry branch of bagging all pollinate twice and column wither, form young fruit after paper bag taken off change nylon net bag into, (specification: long × wide is 80cm-100cm × 30cm-40cm), and tighten sack; After being dried in the sun by sack unbroken in the paper bag displaced, put into carton sealing and save, the coming year is use again, guards against damp damp proof; Sorosis growing period removes field Xun Yuan several times, and inspection is whether the rope of sack is fastened;
<4>, when there is a small amount of atropurpureus shedding at nylon net bag sack place, can start sorosis of gathering; Then, fruit is washed according to a conventional method, kind of drying in the air.
Result: the prematurity shedding amount of statistics two kinds of methods, mellow fruit receive fruit amount and first-filial generation percentage of seedgermination.The survey showed that, and new method of the present invention decreases 5% than conventional method prematurity shedding amount, and mellow fruit receives the raising 15% of fruit amount, and mulberry kind germination rate improves 8%.
