The result shows that: The variation rhythm of the sensitivity index changed unanimously for Jensen,Blank and Stewart water production functions of spring wheat in Liangzhou city,the volume is small in the former stage,then become large at the middle stage,and less at the last stage. Jensen and Stewart water production functions are better of spring wheat in Gulang County in 1987-1989. The Variation rhythm of water deficiency sensitive index is unanimous: the volume are small at first,then large at middle,and diminish at last. The Variation rhythm of water deficiency sensitive index is unanimous in Jensen,Blank and Minhas of flax in Liangzhou county in 1987-1989. The water deficiency sensitive index in Gulang district in 1987-1989 models bad,are too many minus.

If all comes down to the Spring Wheat plantings on Tuesday's 3:00p report. If North Dakota and Minnesota finally got to planting Spring Wheat, the threat of several million acres going unplanted will fade but with a week of dry weather shows no intent we will take out 6.00 and push to 6.22. A break early next week sets up 5.64 as support. To achieve that we need a dry six to ten day forecast and a Tuesday Planting Report over 70% seeded in those two states.

In the whole growth period of spring wheat, the response was different in yield and phase growing on climate change, such as the appearing time of sprouting, jointing, tasselling and maturity being ahead but milking being postponed. That is to say, it shortened the spring wheat's nutrition growth stage of seedingsprouting, elongated the sproutingjointing stage, cut down the generative growth in the jointingtasselling phase, prolonged the tassellingmilking stage, and shortened the milking~maturity stage. These finally resulted in the shortening of whole growth period.
在春小麦整个生长发育过程中,其阶段生长和产量对气候变化的响应不完全一致:气候变化使该地区春小麦出苗期、拔节期、抽穗期和成熟期的出现时间均提前,而乳熟期出现时间推迟,导致播种—出苗期的营养生长阶段缩短、出苗—拔节期的营养生长阶段延长、拔节—抽穗期的生殖生长阶段缩短,抽穗—乳熟期的生殖生长阶段延长,乳熟—成熟期的生殖生长阶段缩短,最终造成全生长期缩短。
