陕西关中西部山旱地胡麻配套栽培技术研究

A High-Yielding Cultivation Technical Package for Flax (Linum usitatissimum L.) in Mountain Dry Farmlands in the West Part of Guanzhong in Shaanxi Province

在陕西省关中西部山旱地连续5年进行胡麻栽培技术研究的结果表明,胡麻产区实施“五攻”综合配套栽培技术——即改不施肥为以施氮肥为主,因地制宜,配方施肥;改农家品种为良种;改稀植为合理密植;改撒播为机条播;改晚播为适期早播,使胡麻亩产从10～20kg提高到55.3kg。该项技术的推广,促进了当地胡麻生产的发展。

The cultivation technical package of flax in the mountain dry farmlandsin the west part of Guanzhong in Shaanxi Province was studied for five years ill succes-sion. The results indicated that the comprehensive cultivation technical package of 'fivechanges' should be implemented in the flax-producing areas; that is: changing non-fertilizer application into N fertilizer chiefly by prescription fertilizaeation suitable to lo-cal conditions; changing the farmer old variety into the fine flay variety; changing thinplanting into rational close planting; changing broadcasting into drilling by seeders; andchanging late sowing into early planting in right time, thus, making the flax yields permu improve from 10-20 kg to 55.3kg. The extension of this cultivation technical pack-age has greatly boosted the development of local flax production.
