The Research On Symposia Bamboo Cultivation Techniques Are From Nan County

Nan County symposia bamboo germless lack of resources, Nan County for large-scale development of bamboo industry to improve people's economic income and Nan County to maintain the ecological environment, Through from the West of Hunan Long Shan County, Sichuan Province and Jiangxi Province.This article made a preliminary exploration of bumper crop cultivate technology of Symposia Bamboos which are from Nan County through the massive field test, We made a system research mainly to the seedling cultivation technology, the forestation technology as well as the tube technology of Cluster Bamboo. The following conclusions:1. Using the method of the field contrast test and randomized complete blocks test to analyze the seedling cultivation technology of Cluster Bamboo. The research analysis result showed:Choose the Neosinoealamus affinisKengf and the Bambusa tewtilis as the mother plants, which should be annual or biennial, the burl bud be quantity,the burl bud and branch bud be plump, the branch be less, stem base be hypertrophy and rich, root system be developed, DBH be 1-8 cm, Bamboo Stem be green, non-plant disease's. Adopting the method of slanting grows seedlings on the loam or the sandy loam to cultivate seedling, and the effect is quite good. The survival rate achieves about 80%, the germination quantity of every seeding achieves about 5 each year, and the bamboo rate achieves above 90%. Adopting the ground cover or employing abscise acid method can make sure the bamboo seeding be exempt from the freeze injury in winter.2. Through the field forestation experiment contrast, the results show that selecting Neosinoealamus affinisKengf and the Bambusa tewtilis that are annual or biennial, and their burl bud be quantity, burl bud and branch bud be plump, branch be less, stem base be hypertrophy and rich, root system be developed, diameter of tree walk boo about 2-5cm, Bamboo stem be green, and non-plant disease's. And adopting the method of Oblique buried stem plant in point, forest in Nan County on the loam or the sandy loam which is loose texture, fertile moist, preserving moisture and fertility the performance good, and non-accumulated water. The forestation effect is good, the survival rate achieves above 85%, the germination quantity of every seeding achieve about 5.5 each year, and the bamboo rate achieves above 90%. 3. Designing field testing by the method of randomized complete blocks test, and using the variance analysis method to carry on the data analysis, can finally obtains: taking the way of trenching buried to fertilize the bamboo grove can effectively enhance the output; interpolating leguminous plant may to support long-short, to plow generation, reduce the moisture evaporation, create moist and breathable soil environment, enhance the soil fertility of the bamboo grove, and then enhance the output.We summarized the supplementary technical measure of high yield cultivation of introduction Symposia bamboo after research and analyze and provided the technical guidance and the theory basis to the vigorous development of the bamboo industry in Nan County.
