山旱区机修田当年种植玉米除采用人为熟化处理、早春抢墒覆膜、裁膜帘式播种外，于玉米苗期5叶和拔节期8叶每公顷喷PP2003、旱地龙及叶面肥，可以消除玉米苗期至拔节期由于气候因素和土壤因素造成的生理缺素症，具有抗旱、促长、平衡玉米植株体内营养分配的作用，促使玉米体内一系列生理功能的协调，从而达到丰产的目的。3年试验结果表明，该处理比人为熟化处理裸地播种生育期提前5个叶龄，产量提高4725kg/hm2，纯收入增加5538元／hm2。比相邻未机修田种植玉米生育期提前2个叶龄，产量提高1773kg/hm2，纯收入增加1156．5元／hm2。
In addition, the cultivation of corn in arid zone of mechanized cultivation of corn in the year except artificial maturation treatment, early spring grab moisture plastic film, cut film curtain sowing, corn and seedling 5 leaves and jointing 8 leaves sprayed per hectare PP2003, dryland and foliar fertilizer, Can eliminate maize seedlings to jointing stage due to climatic and soil factors caused by physiological deficiency syndrome, with drought, promote growth, balance the role of corn plant nutrient distribution and promote maize body to coordinate a series of physiological functions, so as to achieve high yield purpose. The results of three years showed that the treatment was 5 days ahead of the sowing date for artificial maturation, yield 4725kg / hm2 and net income 5538 yuan / hm2. Compared with the adjacent unripe cultivating field, the corn growing period was advanced by 2 leaf ages, the yield increased by 1773kg / hm2 and the net income increased by 1156.5yuan / hm2.
