80年代以来,随着人们生活水平的提高,市场对栗子的需求量不断增长,市场的驱动使得适宜栽培区的栗树迅速发展,甚至成为振兴地方经济的支柱产业.信阳地区一些县(市)出现了大面积栗园,涌现出一批栗树栽培专业户和致富典型.信阳、罗山、新县、光山、潢川、商城等县在栗树生产经营中,除继续更新改造老栗园外,又建立了集中连片、丰产高效的新栗园,为振兴农村经济起到了积极的推动作用.为了充分发挥油栗资源优势,开发利用土地资源,针对油栗生产发展速度快、效益低、栽培技术落后等问题,我站从1991年起开展了豫南大别山区幼龄油栗丰产技术研究,通过不同栽培技术试验,研究油栗栽培经营中的技术难题,并结合示范推广和调查研究,探索出了油栗丰产栽培与实施水保技术的新途径,取得了明显的社会效益和经济效益,在豫南大别山区具有较高的推广价值.1 造林密度对油栗产量的影响从水土保持和经济发展的观点出发,矮冠密植既可有效地控制水土流失,又能提高单位面积产量.为了充分地利用土地空间,在保证栗树速生丰产的同时,可视林冠郁闭程度,适当间种农经作物,提高单位面积经济效益.试验结果表明油栗建园每公顷造林密度以1680～2505株为宜(表1).
Since the 1980s, with the improvement of people’s living standards, the market demand for chestnuts has been continuously increasing, and the market driven the rapid development of chestnut trees suitable for cultivation and even becoming the pillar industries for rejuvenating the local economy. There appeared a large area of chestnut, emerged a group of chestnut cultivation professionals and get rich typical.Xinyang, Luoshan, Xinxian, Guangshan, Huangchuan, Mall and other counties in the production and management of chestnut trees, in addition to continue to update the old chestnut garden , But also set up a contiguous, high yield and efficient new chestnut garden, to revitalize the rural economy has played a positive role in promoting.In order to give full play to the advantages of oil resources, development and utilization of land resources, oil production for the development of fast, low efficiency, Cultivation technology backwardness and other issues, our station from 1991 launched a Dabie Mountain in South Henan young oil chestnut yield technology research, through different cultivation techniques to study oil cultivation and management of technical problems, combined with the demonstration and promotion of research, Explored a new way of high-yield cultivation of oil chestnut and implementation of soil and water conservation techniques, and achieved obvious social and economic benefits. It has a high popularization value in the Dabie Mountains of southern Henan .1 Impact of planting density on oilseed production From the perspective of soil and water conservation and economic development, low density and dense planting can effectively control soil erosion and increase yield per unit area.In order to make full use of the land space, At the same time, we can see the degree of canopy closure and the appropriate cropping of crops and crops to improve the economic efficiency per unit area.The results showed that the plantation density of 1680 ~ 2505 plants per hectare in Oilfield Park was suitable (Table 1).
