Studies On The High Efficiency Cultivation Model Of Poplar Artificial Forest

The application of high efficiency cultivation model of poplar high yield forest can achieve the economics,social and ecological benefits simultaneously , and meanwhile combine the long run and short run economics benefits together. Through cultivation with proper density, manue and water control and multiple exploitation of forest land, ensure the coordinated development of both forestry and agriculture. This study combine the poplar forest with agriculture and animal husbandry in an organic way,achieve the comprehensive utilization both in time and in space.Combine the economic benefit and ecological benefit together, pay attention to economic benefit and the sustainable development of forest land, avoid the land capability decline due to the continuous cropping.This cultivation model breakthrough the traditional ways and cut down on the cost.The net revenue could reach 140 thousand yuan per hectare every year.Enlarge the development space for traditional forestry.Through the study on the experiment site in Gaoqiao forestry plant,Dongshu town,Xiangyin town in Ningyang county, and Hutun town in Feicheng city, we got the result that planting model of 4mâ…¹6m is the best density for poplar of I-107 species, under the local condition, and the optimal rotation is 8 years.There are three types of agro-forest cultivation models for the forest lands multiple uses in the rotation.The first one is plant ginger on the land at the first two years, and plant wheat and soybean at the third year, and then after that, plant mushroom.The net income of this model is 145thousand yuan per hectare,and the production and investment ratio is 1/5.93.The second one is plant wheat and soybean at the first three years ,and then plant mushroom at the rest of the rotation. The average net revenue is 143 thousand yuan per hectare, and production investment ratio is 1/6.17.The third model is plant ginger at the first two years, plant wheat and soybean at the shird year, and then breed chicken for egg production.The average net revenue is 56thousand yuan, and the production investment ratio is 1/3.81.
