| 摘 要： | 试验设计采用9个水分处理,探讨对加工型番茄产童的影响,从而寻求最佳的膜下滴灌灌溉制度.结果表明,随着灌溉定额和滴水次数的增加,产童随之增加,但在番茄需水敏感期(开花期、结果期)滴水次数过少,会严重影响产量.建议试验区加工型番茄膜下滴灌灌溉制度为:滴水1012次,灌溉定额2 1003 000 m3/hm2.

| Abstract: | The fundamental and evaluation method of catastrophe theory were introduced in this paper.The proposed method is easy for calculation and is not necessary to define the weight of evaluation indices,so that the influence of subjective factors on assessment can be minimized.Aimed at disadvantages of normal catastrophe evaluation method,an improved method by adjusting the final comprehensive evaluation values was presented,using polynomial curve fitting.On the base of gained polynomial,the calculated ordinary ... |
