Description
Technical field
The invention belongs to field of ecological planting technology, more specifically relate to the kind method for planting of a kind of tung oil tree (aleurites fordii), be applicable to the tung oil tree plantation of SOUTHERN CHINA knob.
Background technology
Energy scarcity and environmental pollution become the main bottleneck of current world economy sustained and rapid development.Seek, the development and utilization renewable and clean energy resource become global focus.Energy-source plant is a kind of renewable and clean energy resource, is often referred to can produce near oil composition and the product of alternative oil use or the plant of being rich in grease.Energy-source plant can obtain biodiesel through processing.
Tung oil tree is world-renowned industrial oil plant seeds, also is very good energy-source plant, and the oil that squeezes or extract from the tung oil tree seed is referred to as tung oil.Tung oil is the quality raw materials of processing biological diesel-oil.China is the tung oil tree country of origin and main product state, and cultivation utilizes with a long history.The tung oil tree of China's commerial growing mainly is aleurites fordii (Vernicia fordii) at present.Tung oil tree belongs to deciduous tree, is typical tropical trees, requires soil deep, draining is good, loose fertile, moistening neutrality and subacidity plot, the local unfavorable tung oil tree growth of crossing alkali, peracid, sticking heavy, dry barren, ponding is advisable with hilly country cultivation tung oil tree.Tung oil tree happiness light, not anti-the moon, planting site will be selected tailo or half Schattenseite, are advisable with wind sheltering on the sunny side, well-drained gentle slope, and the gradient is with should be below 25 °.The tung oil tree well developed root system, but Root Distribution is more shallow, and main Root Distribution is between 20-40cm.It is bigger that the tung oil tree growth of seedling is influenced by weed growth on every side, before seedling grows into forest, often remove weeds around the seedling.
At present, one of bottleneck of restriction tung oil tree industry development is that paulownia forest products amount is lower, average yield per mu tung oil 15-20 kilogram, also there is a big difference for this and the maximum per mu yield 90-100 kilogram of report, its main cause is that the suitable planting area is narrow, and plant nutrition is produced bad, and survival rate is not high.On the other hand, traditional tung oil tree tillage method has aggravated the hills soil erosion, and soil fertility descends, and tung oil tree output reduces, and causes serious harm for agricultural production and ecotope.Research and explore tung oil tree plantation high-yield culture technique overcomes the problems of ecological security such as liquid manure loss that produce in the tung oil tree planting process, for the development of tung oil tree plant husbandry, improve plantation peasant household economic benefit, preserving the ecological environment all is significant.
Summary of the invention
The objective of the invention is to be to provide the kind method for planting of a kind of tung oil tree, can enlarge the suitable planting district, guarantee the plant healthy growth, improve survival rate, can overcome the problems of ecological security such as liquid manure loss that produce in the tung oil tree planting process again.
