我场遵照毛主席“以粮为纲,全面发展”的伟大方针,利用野生资源较多的有利条件,在山坡、山腰上,已建起板栗林800多亩。但由于缺乏栽培经验,管理水平不高,常年亩产在100斤以下。 1973年我场开展了群众性科学实验活动,建立了三结合的科技小组,针对板栗产量不高的问题,进行了板栗丰产科学试验,摸索栗树生长规律及结果习性,探索板栗丰产的技术措施,培育优质高产栗树。试验林选在林业一队,面积4.2亩,坡向东南,坡度15°,树龄11-14年生,长势中等,品种有处暑红、焦扎、重阳蒲、黄毛蒲、大底青,全园93株,原来单株空蒲率为40％,历年亩产板栗60多斤。1973年经过试验处理后,亩产290.4斤,比当年大 In accordance with the principle of “taking grain as the key link and developing in an all-round way”, Chairman Mao took advantage of the favorable conditions for more wild resources. On the hillside and the mountainside, we have built more than 800 mu of chestnut forest. However, due to the lack of cultivation experience, the management level is not high, perennial mu produce less than 100 pounds. In 1973, we carried out mass scientific experiments and established a three-pronged scientific and technological group. In response to the problem of low yield of chestnut, we conducted scientific experiments on high yield chestnut, explored the growth rules and results of chestnut trees, and explored the technical measures of high yield chestnut , Cultivate high quality and high yield chestnut tree. The experimental forest was selected from a forestry team with an area of ​​4.2 mu and a slope to the southeast with a slope of 15 ° and an age of 11 to 14 years. It grew moderately with 93 species of whole plant, including Zhusha red, Jiaoza, Chongyangpu, Huangmapu, , The original rate of empty plant per plant was 40%, over 60 tons of chestnut per mu over the past years. After testing in 1973, 290.4 kg of mu were produced, which is larger than that of the year
