黄麻密植是增加产量、改进纖維品质的一項重要措施。我省麻区过去栽培黄麻多为稀植,每亩仅种植12,000株左右。从1953年开始推广密植后,密植程度逐年提高。几年来生产实踐証明,黄麻密植是增产的关鍵,特別是大跃进以来,密植增产已成为共同經驗。目前,每亩密度一般已提高到35,000-40,000株。但密植必須配合其他栽培措施,首先要保証全苗,才能真正达到密植增产。一、黄麻密植在生产上的作用 1.增加产量:黄麻是以采收麻皮纖維为目的的作物,适当增加单位面积上的株数,肯定可以提高产量。浙江农业科学院作物育种栽培研究所密植試驗結果証明,种植密度由1.5万株增加到2万、3万和4万株,产量随密植程度的提高而递增,其中4万株的比 Jute density planting is to increase production, improve fiber quality is an important measure. Jade area in our province before the cultivation of mostly jute sparse planting, planting only about 12,000 per acre. From 1953 to promote close planting, planting density increased year by year. Production practice over the past few years has proved that the planting of jute and dense planting is the key to increasing production. Especially since the Great Leap Forward, planting density and increased production have become common experiences. At present, the density per mu has generally increased to 35,000-40,000. However, dense planting must cooperate with other cultivation measures, first of all to ensure that the whole seedlings, in order to truly achieve close planting yield. First, the role of dense planting in the production of jute 1. Increase production: Jute is the purpose of harvesting hemp fiber crops, the appropriate number of units per unit area, will certainly increase the yield. Zhejiang Academy of Agricultural Sciences Crop Breeding and Cultivation Institute close planting test results show that planting density increased from 15,000 to 20,000, 30,000 and 40,000, the yield increased with the degree of close planting, of which 40,000 ratio
