果树密植是提高单位面积产量的重要途径,尤其是提高果园早期产量,增加经济效益更加重要。柑桔果树中,不仅金柑、桔类、柑类适合密植,而树冠高大的橙类也适宜密植。 从1979年外贸部倡导建设全田脐橙出口基地县以来,奉节、秭归、新宁、信丰等县都在努力建设脐橙基地。其中新宁县1980～1982年搞脐橙选种,繁殖苗木,1983年就普遍展开群众性脐橙栽培,至1986年共栽植脐橙1.3万亩,1986年已开花结果达2677亩,总产脐橙500吨(外销357吨)。在建设脐橙基地县的几年中,新宁脐橙就开始了早结丰产新局面,主要是推广了密植与精细栽培管
Close planting of fruit trees is an important way to increase yield per unit area, especially for increasing early output of orchards and increasing economic benefits. Citrus trees, not only kumquat, oranges, oranges suitable for close planting, and tall orange crown also suitable for close planting. Since 1979, when the Ministry of Foreign Trade advocated the construction of Navel Orange Export Base County, Fengxian County, Zigui County, Xinning County, Xinfeng County and other counties are striving to build a navel orange base. Among them, Xinning County engaged in selecting and breeding navel oranges from 1980 to 1982. In 1983, mass-grown navel oranges were commonly cultivated. By 1986, a total of 13,000 mu of navel oranges were planted. In 1986, the fruit had reached 2677 mu Export 357 tons). In the past few years of building navel orange county, Xinning navel orange started a new situation of early harvest and high yield, which mainly promoted the close planting and fine cultivation pipe
