寒地笋玉米栽培技术的研究

Studies on the Cultivation Techniques of multi-ear Special Maize Cultivar in Cold Region

本文通过对笋玉米的栽培技术、施肥水平和两季复种效果的研究，明确了寒地笋玉米的生育特性和栽培技术要点。研究结果证明，宜采用四垄空一垄栽培，亩保苗６０００株左右。亩施基肥磷酸二铵１５公斤，苗期追尿素１０公斤比较经济合理。荷兰豆与笋玉米复种，一年连收两季，经济效益可成倍提高。为使苗齐和采笋期一致，应提倡机播。

Tender un fertiled female ear of maize is a kind of healthy food with high value ofnutrition. When canned,it will have a ready market at home and abroad, so it has a good development prospect. Through the studies on cultivation techniques. fertilizer appl icationmethods and double-cropping effect of multi-ears special maize cultivars. We have a goodcommand of the growth and development features and key point of cultivation techniques onthem. The experimental results showed that the pattern of four rows with an intervel rowwas the suitable tillage pattern and the best density was 6000 plants per mud that it was eecmomic and reasonal to apply diammonium phosphate 15 kg per mu be for planting and to topdress urea 10 kg per mu. And that the economic benefits could be increased doubly by meansof multi-ears special maize cultivar double-cropping with pea. In order to get uniformseedlings and the same tender un fertiled female ear harvesting stage. machine-sowing isrecommended.
