The cultivation method includes the steps that mulberry resources prone to rooting are surveyed and collected; the mulberry varieties prone to rooting are cut and bred; radiomutation strains are selected; large-field cuttage and general selection are conducted. The invention further disclosed a quick garden building method of the mulberry varieties for cuttage based on the cultivation method of the mulberry varieties for cuttage. The quick garden building method includes the steps of cutting preparation, mulberry planting land parcel selection, planting specification determination, field planting land trimming, sectional branch cutting, cuttage and fertility management. Breeding, variety comparison and demonstration are conducted in an induced mutation by radiation mode, the mulberry varieties which are prone to rooting, high in leaf yield and good in leaf quality are selected, a main root obviously formed through cuttage is hard in woodiness, good in leaf quality and high in leaf yield, temperature control and hormone treatment are not needed, and the cuttage survival rate reaches 90% in a natural state.
Description
Technical field
The present invention relates to planting technology field, specifically, refer to cultivation and the quick garden building method of a kind of cuttage mulberry races.
Background technology
Along with the development that silkworm and mulberry are produced, in mulberry races seed selection, require to select high resistance, fertilizing amount is few relatively, and extensive management reduces the mulberry tree breed of investing, to adapt to the needs of silkworm and mulberry production development.There are the eighties refined all mulberry cuttages easily to take root, Yi Bucheng garden mulberry cultivation technology, though refined all mulberry rooting abilities are strong, the root forming is fibrous root, root system can not go deep into soil layer depths, plantation 2-3, leaf yield can decline, and wooden loose, being subject to mulberry longicorn causes harm, the food value of leaf is also poor, to the nineties, is eliminated gradually, seldom utilizes at present on producing.Hard of the nineties, green wood cutting, and give preference temperature or root-promoting hormone processing.Enter after 2000, people start the seed selection cuttage mulberry tree breed of easily taking root.As " Shandong insert No. 1 " cultivated in the silkworm industry research of academy of agricultural sciences of Shandong Province, and continue to continue to use and give preference temperature or root-promoting hormone processing the nineties.Mulberry sapling breeding, for the sowing of mulberry seed, cultivates seedling under normal circumstances, then through changing kind, whole process approximately needs triennium to going into operation.Sport technique segment is many, takes a lot of work, time-consuming, increases cost.
Insert Shandong is for No. 1 the triploid cuttage mulberry tree breed of easily taking root that Sericultural Research Institute of Shandong cultivates, and hands over the seed selection of 4 times of body filial generations to form by 2 times of bodies.Parent is selected, and except requiring ploidy, also will consider cuttage root-taking proterties." insert No. 1 Shandong " kind needs to ventilate and urge root under daylight hotbed, and cuttage and seedling culture survival rate just can reach degree of being practical, need to be by ventilating and urge root device under daylight hotbed.Wang Lin, 1996 rooting-speeding technology for mulberry cuttage patents, Cheng Jia tail feather, stereo raise seedling method patent and the Xu Chengmei etc. of 2010 mulberry saplings, New Mulberry Variety green wood cutting Ji Yibujian garden technology, these technology, all will pass through mulberry tree root of hair principle, adopt corresponding temperature control, wet technical finesse.Hunan silkworm and mulberry research institute, 1989-1991 mulberry tree fast seedling growing technology; Wang Lin, 1996 Mulberry Cuttage new technologies; Zhang Shihua and Wang Yonghong, No. 2 cuttages of 2013 mulberry tree breed cloud mulberries, all will pass through hormone " ABT root-inducing powder " technical finesse, impel mulberry branch to take root, and controlled condition is strict, operates loaded down with trivial details.Otherwise do not reach degree of being practical.
Summary of the invention
The object of the present invention is to provide cultivation and the quick garden building method of a kind of cuttage mulberry races, can overcome above-mentioned defect, by adopting radioinduction mode to carry out breeding, product ratio, demonstration, select that cuttage is easily taken root, leaf yield is high, the food value of leaf good and cuttage obviously forms main root, wooden hard, the food value of leaf is good, and leaf yield is high, does not need temperature control and HORMONE TREATMENT, under nature, cuttage survival rate reaches 90%.
The present invention is achieved through the following technical solutions:
A breeding method for mulberry races for cuttage, comprises the following steps:
(1) investigate and collect the Morus alba Resource Development of easily taking root: select Sri Lanka mulberry;
(2) the cuttage mulberry tree breed seed selection of easily taking root: comprise the following steps:

1carry out simple bud grafting for branch, after germinateing, note erasing the primary bud-leaf on stock plant, select in the fall the fine individual plant approaching with breeding goal; Mutagenesis two generations (V
2) be the maximum generation of variation, be also the critical period of selecting;
(2.3) land for growing field crops cuttage general election: mid or late March, when ground temperature reaches more than 12 degrees Celsius, by the V obtaining in step (2.2.2)
2in generation, is carried out land for growing field crops cuttage general election, and therefrom selection possesses the good individual plant emphasis cultivation breedings of Comprehensive Traits such as high-quality, high yield, easy cuttage.
Inventor successively investigates Yaan, Sichuan Province, Lushan, day complete, Yingjing, Ningnan, Laifeng County, Hubei, Hainan Island Ba Wangling, Jianfengling, national geological parks, volcanic crater, San Ya city, and the mulberry tree cuttage such as Sri Lanka repository of easily taking root.Easily take root more than 20 part of Morus alba Resource Development of Collection and conservation cuttage.More than the 20 parts of cuttages Morus alba Resource Development of easily taking root has been carried out to biological property, economic characters and rooting ability investigation, found that Sri Lanka's mulberry matter is harder, rooting ability is strong, and can form main root, cuttage survival rate is high, and resistant to diseases and insects is strong, is particularly suitable for cuttage and uses, but it is thinner that its shortcoming is blade, output is not remarkable, is expected, by means such as radiation-induced and chemical inductions, it is carried out to systematic breeding, improves its food value of leaf and output, reach high-quality, high yield, easily cuttage, the effect that high yield period is long.Within 2012, carry out
60the mutation breeding of co-gamma Rays.
Radiaction mutation is a kind of important breeding technique, and its major advantage is can batch process, variation frequency is high, stably and rapidly, method is easy.Different mulberry tree breed radiation-sensitive degree are different, generally 5000---and between 7500 roentgens, be dose,optimum, exceed 7500 roentgen's survival rates and just significantly reduce.The experiment proved that, use
60co-gamma-rays carries out Continuous irradiation 5 hours, can improve the survival rate after radiation, greatly increases the selection probability of variation branch section, improves breeding efficiency.The present invention selects by accumulated dose 5500 roentgens, and the standard of dose rate 1100 roentgens/h is used mulberry tree fringe bar and winter bar
60co-gamma-rays carries out Continuous irradiation, proves through production practices, and after radiation, survival rate can reach 78.4%, can greatly increase the selection probability of variation branch section, improves breeding efficiency.Owing to being subject to inhibition and the damage of ray, the germination rate in V1 generation is generally lower, and banded branch section, phenomenon without leaf branch section or bifurcated branch section appear in development delay, passing in time, and it is normal that shoot and leaf growth recovers gradually.
The present invention is the ground demonstration such as in river oil, Leshan in 2013, selected variant, and cuttage survival rate reaches 91%, and output is high, saves and plants 1000.00 yuan/0.067 hectare of mulberry seedling cost, possesses the feature that high-quality, high yield, cuttage are easily taken root.
