1品种选择选择苗期耐低温、种子拱土能力强、籽粒灌浆和脱水快、较抗旱的玉米品种。苗期耐低温、早发性好的品种,能充分利用前期光热条件;籽粒灌浆和脱水快能够躲避和减轻低温早霜的影响。在中、下等肥力,尤其沙性土壤应种植稀植或半耐密中熟耐旱品种;在肥力较高、有机肥及化肥投入水平高及有灌水条件的地块,可以适当选择种植耐密、半耐密中熟或中晚熟高产品种。
A variety of options to choose seedling low temperature, seed arching ability, grain filling and dehydration faster, drought-resistant varieties of corn. Low seedling temperature, good early-onset varieties, can make full use of pre-photothermal conditions; grain filling and dehydration can quickly avoid and reduce the impact of low temperature early frost. In the middle and lower fertility, especially sandy soil should be planted with thin planting or semi-dense medium maturity drought tolerant varieties; in the high fertility, organic fertilizer and fertilizer input levels and irrigation conditions of the plots, you can choose the appropriate planting tolerance Dense, semi-dense medium or late maturing varieties of high yield.
