山东省冠县苗圃梨树密植试验小组,是近几年成长起来的一支群众性的科技队伍。在短短的几年中,他们顶住“四人帮”的干扰破坏,大搞科学实验取得了显著成绩。开始他们搞了1.2亩梨树密植试验地,用土生土长、资源丰富、适应性强的杜梨乔化砧木,嫁接优良的鸭梨品种(主栽品种),又安排了嫁接茌梨、香水梨、砀山酥梨等品种作为授粉树。每亩栽种梨树459株。在1975年,四年生梨树获得了亩产8,711斤的好收成;1976年,又获得了10,043斤的产量。现在这一试验成果正在由点到面,对梨树矮化密植早期丰产起了示范作用。这个试验小组,在深入总结群众管理经验的基础
Guan County, Shandong Province pear close planting test group, is growing in recent years, a mass of scientific and technological personnel. In just a few years, they have made remarkable achievements in resisting the “gang of four” interference and sabotage and conducting scientific experiments. Beginning they engage in 1.2 acres of pear close planting test sites, with indigenous, resource-rich, adaptable Du pear Joe rootstocks, grafted varieties of pear (cultivar), and arranged grafted pear, pear, Dangshan pear varieties such as pollination tree. 459 pear trees planted per mu. In 1975, the four-year-old pear tree received a good harvest of 8,711 pounds per mu; in 1976, it gained an additional 10,043 pounds. Now the result of this experiment is from the point to the surface, the dwarf and dense planting early pear yield has played an exemplary role. This experimental group, in-depth summary of the basis of the masses management experience
