从豫西旱地生态条件谈旱作小麦增产技术

针对豫西丘陵旱作区小麦生长期内降水少,土壤干旱,施肥量少,土壤瘠薄,水土流失严重,小麦耕作管理粗放,产量低而土稳的实际,分析了旱作小麦生长发育特点,提出了实现旱作区小麦增产的主要技术:深耕蓄水、以肥调水、以种节水、以管保水的“四水一早”栽培技术,和“开沟点播、地膜覆盖、干籽寄种”旱地小麦播种技术。

Discussion on Technology to Raising Yields of Wheat Planted in Hilly Dry Land in the West of Henan Province According to Its Ecological Conditions

s: On the hill dry land of the west of Henan province, China, little precipitation, drought and barren soil, a small quantity of fertilizer application, and serious water loss resulted in low and changeful yields of wheat plants. Combinations of the above ecological conditions with characteristics of wheat plants, we proposed some ways to raise wheat yields in this region. The planting ways of "four water and one early" included deep plough to hold rainwater, more fertilizer application to supple water, more seeds to save water, good mange to decrease water loss. And the seeding ways were mainly: ditching seeds in the field, the plastic-mulching cultivation and drought-resistant sowing.
