关中棉区转基因抗虫棉简化栽培关键技术研究

Key Technique of Simple Cultivation for Transgenic Resist-pest Cotton in Middle Shaanxi

论述了关中棉区转基因抗虫棉的简化栽培技术。以重施基肥,稳氮增磷增钾,化学除草,初花期水﹑肥﹑控同步,沟灌节水,简化整枝及化学催熟等项技术组装配套,达到节支省工,提高整体经济效益。

The simple cultivating technique of transgenic resist-pest cotton was discussed in this paper.In order to decrease expenditure and increase total economic efficiency, the key technique consisted of a complete sets of base fertilizer heavily, stabilizing N, increasing P and K, herbicide, coordinating of irrigation, fertilization and DPC regulation in first-flowering time, water-saving by furrow irrigation, simple pruning of cotton plants, chemical accelerating the ripening and so on.
