玉米品种;根水势;抗旱性;隶属度
摘  要：
通过对农大108等玉米品种幼苗阶段不同时期根系水势的测定,并用模糊数学隶属度的公式进行转换,用各品种不同时期隶属度的平均值来评价每个品种抗旱性强弱。结果表明:郑单958(豫玉33号)属特抗旱类型品种;030×104、农大108(ck)、065×150、040×111、655×8号属抗旱类型品种。在水源不足的玉米生产区应加大推广力度,尽量缩小抗旱性能较差品种的种植面积,提高经济效益。

摘  要：
In this article,we first test "Nongda108"etc several corn varieties' water potential of their roots in seeding stage but in different child-bearing.Then we transit the different stage's test value by using the formula of membership grade in fuzzy mathematics.So we can evaluate the every corn variety drought-resistance by using each corn variety different stage's average value of membership grade.The results express that("Zhengdan 958") belongs to a species of hith anti-drought corn variety;"Nongda 108,030×104,065×150,(040×111),655×8"belong to the type of anti-drought corn variety.Therefore,we should take great action to popularize the anti-drought varieties in areas lacking water source,decrease the area of planting for such varieties with a worse drough resistence as quickly as possible,so as to raise the economic benefit.
