Description

The cultivation method of the mulberry tree of self-restraint Karst Mountains Desertification Area
Technical field
The present invention relates to the cultivation method of economic plants, particularly conserve the cultivation method of the mulberry tree of Karst Mountains Desertification Area.
Background technology
The a lot of provinces, cities and autonomous regions of south China, as there is a lot of Karst hills area on the ground such as Guangxi, Guizhou, Yunnan, Guangdong, Jiangxi.The feature in Karst hill area is that the water with corrosion power carries out earth's surface that the effects such as corrosion form and the general name of underground form to solublerock, claims 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, virgin forest coverage rate is high, aboundresources, beautiful scenery, but along with the growth of entrance, the mankind are in Karst hill area Fast Activities, just cause 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, due to the unreasonable exploitation of locals to land resources, cause vegetation deterioration, water and soil loss, land capability decline or lose, rock is exposed gradually, and earth's surface presents similar desertscape.At present, nearly more than 70% Rocky desertification hazard of China is mainly distributed in southern 8 provinces (district, city) such as Guizhou centered by Guizhou Plateau, Yunnan, Guangxi, Hunan, Hubei, Chongqing, Sichuan, Guangdong, stony desertification area reaches 12.96 ten thousand square kilometres, annual land area of approximately engulfing 1856 square kilometres, is totally aggravation trend.
For intensity Rocky Desertification Region, because the relation of human and environment is seriously lacked of proper care, the mankind lack basic life condition, therefore the improvement of stony desertification is mainly taked to naturally revert to main ecology 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 moderate Rocky Desertification Region, mainly taking to administer is main ecology 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 ecology 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 scientific research and practice for many years, people start to recognize Rocky Desertification Region plantation mulberry tree be one 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 basic status self-sow in 200 millimeters of upper and lower arid-desert areas 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.There is the root system network of water storage function, have extremely strong containment dust storm, the ability conserving water and soil.Root turion ability is strong, resistance to felling.The resistance of mulberry tree, can bear the high temperature of 40 ℃, the low temperature that ability is subzero 35 ℃.Soil pH value all can be grown between 4.5~8.5, and soil salt content can normal growth 0.2% time.Therefore mulberry tree, to soil, has very wide adaptability to weather, and easily breeding, brings convenience to spread, and it has become planting trees on barren hills, the pioneer tree species of checking winds and fixing drifting sand.Mulberry leaf, except breeding silkworms, can also be served as the good feed of cowboying, sheep raising
In some areas in Guangxi Hechi, Yizhou and the Guizhou Province of Southwestern China, there is the experience of successfully planting mulberry tree, for example Guangxi Can Ye director in Donglan County, Guangxi, Fengshan County carried out pilot, obtain good achievement, but, how to plant 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 object of this invention is to provide the cultivation method of a kind of mulberry tree of conserving Karst Mountains Desertification Area, make it to become planting trees on barren hills, windproof solid native pioneer tree species.Mulberry leaf, except breeding silkworms, can also be served as the good feed of cowboying, sheep raising, bring Revegetation of Eco-environment and increase income to mass peasants to Karst hill area.
The cultivation method of the mulberry tree of self-restraint Karst Mountains Desertification Area of the present invention comprises the following steps:
1, breed breeding.
Choose the good mulberry tree breed of the good mulberry tree breed in the cold-resistant north and south drought-enduring, impoverishment tolerant and hybridize or grafting, obtain being applicable to the mulberry tree breed of Karst Mountains Desertification Area.The present invention adopts " Gui Sang excellent 62 " as stock; No. 10, farming and sericulture is as scion.
The excellent 62(original name of Gui Sang: osmanthus assorted excellent 62) be that Guangxi Can Ye Technique Popularizing master station bears the mulberry tree new cross combination (Hybrid Mulberry) that autonomous region " 95 " brainstorm project seed selection becomes, within 2000, pass through the authorization of the Crop breed audit committee of autonomous region.Variety certification numbering: card word is examined No. 161 in osmanthus, this kind has that colony is neat, branch number is more, branch Gao Jiemi, leaf great Ye thick, resistance to cut cut down, germinate early, receive make more late, mosaic disease resisting is stronger, drought-enduring heat-resisting ability is strong, leaf yield is higher, breed easier, suitable conventional cultivation, also suitable fast growing Labor-saving cultivation.Its leaf yield increases production 19.32% than existing high yield mulberry races sand 2 × human relations 109, 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 sericulture of just can going into operation then of sowing then, sows next year to enter high yield period.This mulberry races (combination), in the large scale application of various places, Guangxi, is subject to general welcome.On February 19th, 2000, Guangxi crop varietal approval committee was passed through.Gui Sang excellent 62 is that it is the kind that Guangxi local is cultivated as the reason of stock, adapts to the amblent air temperature in Guangxi, well developed root system, and Karst Mountains Desertification Area is relatively applicable to plantation.
No. 10, farming and sericulture, No. 10 mulberry treies of farming and sericulture are that the Tongxiang green grass or young crops/human relations religion of academy of agricultural sciences of Zhejiang Province is done parent No. 109, form in seed selection in 1989.The authorization in 1996 of the Crop breed audit committee of Zhejiang Province.
No. 10, farming and sericulture is tree-like upright, tree crown compactness, and branch is long and straight, and color of the leather is steel gray, and branch base portion joint shape is outstanding, and root substance is obvious, phyllotaxy 3/8, hole skin yellowish-brown, circle or oval, hibernaculum Yangtze River Delta shape, sepia, leaf oblong, leaf bottle green, opens male flower.Early raw early-maturing variety.
Characteristic: Hangzhou cultivation, germination period March 14~18, germination rate 75%~80%, main bud endure cold after accessory bud can sprout, generally do not affect spring leaf-making quantity, on March 24~28 leaf opened setate, on April 15~20 blade maturing stage, belong to early raw early-maturing variety.The long leaf yield 177g of every meter of bar in spring, 275 of kilogram numbers of blade, blade accounts for 54% of bar, the tip, leaf gross weight; The long leaf yield 143g of every meter of bar in autumn, 182 of kilogram numbers of blade, bind all slower with blade sclerosis.
Regional test result: 1991~1994 Zhejiang Province's third phase New Mulberry Variety regional test results, annual mu mulberry leaf yield 2135kg, than control group " lotus leaf is white " volume increase 17.1%, wherein phase in spring per mu yield sheet leaf amount 986kg, than contrast volume increase 23.1%.Ten thousand silkworms produce cocoon layer 4.0kg, higher by 2.7% than contrast; Mu mulberry produces cocoon shell weight higher than contrast; 40958 of the good ovum numbers of hundred silkworms are lower by 1.0% than contrast.Mulberry epidemic disease disease index is 1.7, and contrast is 4.3; The mulberry yellow dwarf disease strain incidence of disease is 0, identical with contrast.Through significance test, annual mu mulberry leaf yield and phase in spring per mu yield sheet leaf amount all significantly exceed contrast, and ten thousand silkworms produce cocoon shell weight, the good ovum number of hundred silkworms and contrast without significant difference.The resistance of mulberry epidemic disease is better than to contrast strong, to mulberry yellow dwarf disease resistance with contrast similar.Farming and sericulture is for No. 10 a precocity, high yield, disease-resistant, preferably New Mulberry Variety of the food value of leaf.
Output performance: participate in the regional evaluation of Zhejiang Province's mulberry races for 1990~1994 years, a mu mulberry leaf yield reaches 2135Kg, and higher by 17.1% than contrast kind of " lotus leaf is white ", wherein spring per mu yield sheet leaf amount 985.5Kg, higher by 23.1% than " lotus leaf is white ".
This kind should, in the good Plain plantation of liquid manure, should not be planted in hilly and mountainous land.So Karst Rocky Desertification mountain region can not be served as directly and planted as cuttings.
2, wholely.
Should be chosen in soil thickness and be that 30 centimetres above, the soil is porous, drainage and good air permeability, tailo, half light hillside fields section that illumination condition is good be better, is generally 40~100 centimetres, dark 30~50 centimetres if plot is strip soil preparation bandwidth; Belt length is determined according to landform, should retain at a certain distance 50~100 centimetres of natural vegetations, if plot is block (cave is cultivated), regular size has: 40 40 centimetres of cm x 40 cm x, 50 50 centimetres of cm x 50 cm x, centered by kind of plant hole, remove shrubbery and the weeds of surrounding, cleaning scope is determined according to the size of whole ground specification; Gesture forms terraced fields near the mountain.
3, grow seedlings and grafting.
Because Karst Mountains Desertification Area is more arid, live stock growth is slower, so need to carry out live in fertile field, Plain, " Gui Sang excellent 62 " mulberry tree breed is 2-3 in spring month seed sowing, live plant excellent 62 seedling of Gui Sang and generally want trunk to grow to the just grafting of chopsticks size, adopt then or the live seedling of the previous year can grafting; Or after cuttage and seedling culture 1 year as stock.
The scion that No. 10, farming and sericulture can adopt cuttage and seedling culture, the 2-3 month is carried out cuttage in fertile field, Plain, the fringe bar clip before the Spring Festival of propagation by grafiting, trunk grows to chopsticks size can carry out grafting, grafting method can adopt fringe connection or tooth connection, and fringe to be grafted survives and grows 5 centimetres of left and right and can transplant.
