Research On Cultivation Technology Of Xanthoceras Sorbifolia Bunge In Low Mountainous Upland Region Of Western Liaoning

This article researched on the Xanthoceras sorbifolia Bunge of seedling growth, flowering and fruiting,fertilization technology,and a variety of business model,the results showed that:(1)When the seed soaking temperature is 80?,the germination percentage and germination potentiality of Xanthoceras sorbifolia Bunge is best.Xanthoceras sorbifolia Bunge 1 year average in 0.66m,plant height is the fastest growth rate.Its biomass size of each part is root> trunk> leaf> branch, the largest part of the moisture content is the leaves.The plant height,diameter at breast height and biomass of each part can establish mathematical model.(2)During the blooming period,the wind speed is the key factor influencing the fruit setting rate of Xanthoceras sorbifolia Bunge; light intensity is strongly associated with the quality of the flower and the fruit maturation rate;the air temperature have important effect on the flowering dates and fruit size of Xanthoceras sorbifolia Bunge, and the air humidity is not significant.Soil temperature influence the nutrients transport,mainly displays in the bud and blossom and bear fruit mature period;the high soil moisture can intake the type of flower,fruit and seed weight and the yield of single tree;soil available nitrogen is promoting the quantity and quality of flowers and the average yiled.The principle component analysis to environmental factors of flowering and fruiting of Xanthoceras sorbifolia Bunge,soil moisture and air temperature are the dominant factors.(3)The experiment of orthogonal design of Xanthoceras sorbifolia Bunge, can be concluded that the most suitable for the fertilizer combination.nitrogen,216 g/plant;phosphorus,72g/plant;potash,172g/plant.Nitrogen fertilizer has significant effects on the height,canopy,ground diameter and chlorophyll content.There is a direct relationship between leaf nutrient content,soil nutrient content,production and nitrogen, phosphorus,potash fertilizer.(4)The largest tree height,canopy,ground diameter growth is the monoculture of Xanthoceras sorbifolia Bunge,followed by the intercropping mode.Vertically,soil nutrient changes decrease with the increase of soil depth;in the horizontal direction,soil nutrient content of the intercropping mode is better the monoculture.The production of monoculture of Xanthoceras sorbifolia Bunge is the highest;land use efficiency,the intercropping system than monoculture system increased by 61.34% and 61.34%.
