Description

The cultivation method of Karst Rocky Desertification mountain region mulberry tree
Technical field
The present invention relates to the cultivation method of economic plants, the cultivation method of the mulberry tree of particularly breeding silkworms
Background technology
There is a lot of Karst hills area in a lot of provinces, cities and autonomous regions of south China such as Guangxi, Guizhou, Yunnan, Guangdong, Jiangxi and other places.The characteristics in Karst hill area are water with corrosion power carries out the formed earth's surface of effect such as corrosion and underground form to solublerock general names, claim again karst features.Except corrosion, also comprise the erosion of flowing water, the erosion of diving, and the mechanical erosion process such as collapse.Before centuries, the Karst hill area rainfall of south China is abundant, have abundant water resources, the virgin forest coverage rate is high, aboundresources, beautiful scenery, but the growth along with entrance, human in Karst hill area Fast Activities, just caused the destruction of mountain areas forest, the Karst Desertification of Southwestern China karst has been one of the most serious environment in the current whole world and socioeconomic problem at present, when we are having a taste of karst stone forests in different poses and with different expressions and stone forest wonder, after the superb craftsmanship of admiration the Nature, hardly realize that Karst Rocky Desertification engulfing our home just gradually, threatening our production and life.Under the fragile ecological environment of karst, because the locals, causes vegetation deterioration, water and soil loss, land capability decline or forfeiture to the unreasonable exploitation of land resources, rock is exposed gradually, and the earth's surface presents similar desertscape.At present, the nearly Rocky desertification hazard more than 70% of China mainly is distributed in southern 8 provinces such as Guizhou centered by Guizhou Plateau, Yunnan, Guangxi, Hunan, Hubei, Chongqing, Sichuan, Guangdong (district, city), the stony desertification area reaches 12.96 ten thousand square kilometres, annual land area of approximately engulfing 1856 square kilometres totally is aggravation trend.
For the intensity Rocky Desertification Region, because the relation of human and environment is seriously lacked of proper care, the basic life condition of human shortage, therefore the improvement of stony desertification is mainly taked naturally to revert to main ecological strategy, except planned, do systematically Ecological Immigration, the measure such as take to close hillsides to facilitate afforestation progressively recovers vegetation, and the eco-tour of reasonable development karst.For the moderate Rocky Desertification Region, mainly taking to administer is main ecological strategy, actively administers by conceding the land to forestry, develop the measures such as farm forestry.For slight Rocky Desertification Region; mainly taking to administer is ecological strategy main, that strengthen prevention; carry out the Comprehensive ecological control of the ecological agriculture, courtyard economy; strengthen farmland capital construction, rural energy construction and man and livestock drinking water project construction; protect existing soil and vegetation cover, prevent new stony desertification soil.
After through for many years scientific research and practice, people begin to recognize Rocky Desertification Region plantation mulberry tree be a kind of can planting trees on barren hills, Revegetation of Eco-environment, can develop again Sericulture, livestock breeding and the development outlet of fancy fruit (mulberry fruit) is provided, through investigating, it is found that the botany characteristic of mulberry tree, determined its ecological functions.The vitality of mulberry tree is extremely vigorous, still can grow with the basic status self-sow at 200 millimeters arid-desert areas up and down of precipitation.The root system of mulberry tree is very flourishing, and root system nature expanded area is several times and even tens times of tree crown projected area.The root system network that the water storage function is arranged has extremely strong containment dust storm, the ability that conserves water and soil.The root turion ability is strong, anti-felling.The resistance of mulberry tree can be born 40 ℃ high temperature, the low temperature that ability is subzero 35 ℃.Soil pH value all can be grown between 4.5~8.5, but soil salt content normal growth 0.2% time.Therefore mulberry tree has very wide adaptability to soil to weather, and breeding brings convenience to spread easily, and it has become planting trees on barren hills, the pioneer tree species of checking winds and fixing drifting sand.Mulberry leaf can also be as the good feed of cowboying, sheep raising except breeding silkworms
Some areas in Guangxi Hechi, Yizhou and the Guizhou Province of Southwestern China, the experience of successfully planting mulberry tree has been arranged, for example Guangxi silkworm industry director in the Donglan County, Guangxi, the Fengshan County carried out pilot, obtained preferably achievement, but, how to plant the high-quality mulberry tree in the more serious area of stony desertification, promote the development of sericulture and stable breeding cattle and sheep to also have a lot of work to do
Summary of the invention
The purpose of this invention is to provide a kind of variety culture method that is adapted at Karst Rocky Desertification mountain region mulberry tree, make it to become planting trees on barren hills, the pioneer tree species of windproof solid soil.Mulberry leaf can also be as the good feed of cowboying, sheep raising except breeding silkworms, and brings Revegetation of Eco-environment and increase income to mass peasants for the Karst hill area.
The cultivation method of Karst Rocky Desertification of the present invention mountain region mulberry tree may further comprise the steps:
1, breed breeding
Choose cold-resistant northern good mulberry tree breed and southern good mulberry tree breed drought-enduring, impoverishment tolerant is hybridized or grafting, obtain being fit to the mulberry tree breed of Karst Mountains Desertification Area.The present invention adopts " Gui Sang excellent 62 " as stock; "Hur" mulberry series is as scion.
The excellent 62(original name of Gui Sang: be that Guangxi silkworm industry Technique Popularizing master station bears the mulberry tree new cross combination (Hybrid Mulberry) that autonomous region " 95 " brainstorm project seed selection becomes osmanthus assorted excellent 62), passed through the authorization of the Crop breed audit committee of autonomous region in 2000.Variety certification numbering: the card word is examined No. 161 in osmanthus, this kind has that colony is neat, the branch number is more, branch Gao Jiemi, leaf Da Ye thick, anti-cut cut down, germinate early, receive make that evening, stronger, the drought-enduring heat-resisting ability of mosaic disease resisting are strong, leaf yield is higher, breed easily, suitable conventional cultivation, also suitable fast growing Labor-saving cultivation.Its leaf yield is than existing high yield mulberry races sand 2 * human relations 109 volume increase 19.32%, and per hectare mulberry field leaf yield reaches as high as 60 tons, and 8.63 kilograms, hundred kilograms mulberry leaf of hundred kilograms of mulberry leaf amount of cocoon crop produce 1.85 kilograms of cocoon shell weights.Utilize seminal propagation, also can live Cheng Yuan, the then sowing sericulture of just can going into operation is then sowed next year to enter high yield period.This mulberry races (combination) is subject to general welcome in the large scale application of various places, Guangxi.On February 19th, 2000, the Guangxi crop varietal approval committee was passed through.Gui Sang excellent 62 reasons as stock are that it is the kind that Guangxi local is cultivated, and adapt to the amblent air temperature in Guangxi, and well developed root system, Karst Mountains Desertification Area relatively are fit to plantation.
"Hur" mulberry series is Zhejiang Province's high-quality mulberry tree breed, is Zhejiang Province's important mulberry tree breed on the ground such as Huzhou, Hangzhou, Wenzhou particularly, comprise "Hur" mulberry No. 32 (also claiming that lotus leaf is white) or silkworm special No. 4 as scion.
No. 32 kinds of "Hur" mulberry originate in Haining, Zhejiang Province county, feature: the tree type is tall and big, and clockwork spring is many, and branch is thick and crooked.It is heart-shaped that leaf is, leaf color jade green, and the blade face is smooth, and blade is large, and mesophyll is thick, and leaf yield is high, and the food value of leaf is good, and it is slower to germinate, and belongs to late variety.The autumn leaves sclerosis is late, and is wooden hard, strong adaptability, and moisture-proof, Salt And Alkali Tolerance, drought resisting, cold-resistant, anti-atrophic type, mosaic dwarf disease, anti-brown spot, bacteriosis and dirty leaf disease."Hur" mulberry 32 leaf yields are high, and the food value of leaf is good, and the sclerosis in autumn is suitable for several times a year picking leaves and feeds silkworm late, and Zhejiang Province is the ground of the high-quality silk of China, gets "Hur" mulberry series as scion, can improve the silk quality of silkworm worm.
Special No. 4 of silkworm, variety certification numbering: state examines silkworm and mulberry 2001001, seed selection unit: University Of Suzhou, silkworm and mulberry station, Wujiang, silkworm and mulberry station, Wuxian, cultivar origin: the natural crossing mulberry of growing directly from seeds.Leaf yield improved 15% No. 32 than "Hur" mulberry in the examination investigation of urban district, Wujiang in 1991~1994 years; Raw cocoon production amount of cocoon crop, cocoon shell weight and parent silkworm rearing list moth egg number improve about 10% No. 32 than "Hur" mulberry; Total reducing sugar, crude protein, crude fat improve about 13~15% No. 32 than "Hur" mulberry, and conversion rate of silk leaves improves about 16%.
Above-mentioned " "Hur" mulberry No. 32 " or " special No. 4 of silkworm " should in the good Plain plantation of liquid manure, should not be planted in hilly and mountainous land.So the Karst Rocky Desertification mountain region can not be as directly planting as plugged ear.
, whole ground
Should be chosen in soil thickness and be more than 30 centimetres, the soil is porous, drainage and good air permeability, tailo, half light hillside fields section that illumination condition is good are better, is generally 40~100 centimetres if the plot is the strip soil preparation bandwidth, dark 30~50 centimetres; Belt length is determined according to landform, should keep at a certain distance 50~100 centimetres of natural vegetations, if the plot is block (cave is cultivated), regular size has: 40 centimetres of 40 cm x, 40 cm x, 50 centimetres of 50 cm x, 50 cm x, centered by kind of plant hole, shrubbery and weeds around removing, the cleaning scope is decided according to the size of whole ground specification; Gesture forms terraced fields near the mountain.
, grow seedlings and grafting
Because Karst Mountains Desertification Area is arid, live stock growth is slower, so need to carry out live in fertile field, Plain, " Gui Sang excellent 62 " mulberry tree breed is the 2-3 month in spring to use seed sowing, live plant excellent 62 seedling of Gui Sang and generally want trunk long to the just grafting of chopsticks size, adopt then or the live seedling of the previous year can grafting; Perhaps after the cuttage and seedling culture 1 year as stock
The scion of "Hur" mulberry series can be adopted cuttage and seedling culture, the 2-3 month is carried out cuttage in fertile field, Plain, the fringe bar of propagation by grafiting is clip before the Spring Festival, trunk is long can to carry out grafting to the chopsticks size, grafting method can adopt fringe connection or tooth connection, and fringe to be grafted survives and grows about 5 centimetres and can transplant.
, nursery stock processes: stay 2-5 buds more than grafting fringe place, be about 20cm, remainder cuts off, and the part fibrous root cut off, will can add an amount of peroxophosphoric acid calcareous fertilisers during the slurry root with fertile pond sludge or stream mud slurry root simultaneously, the slurry root is the key that improves survival rate.
, the plantation
