According to the wide application of the valuation of the bill of quantities,it compares the valuation of the bill of quantities and quota valuation from counts and measurement,points out that their making procedure and cost constitution is almost the same,and compares the main calculation rules of different programs from architectural project and decoration design.

In this paper,in order to explore the fit cultural techniques,the yield and yield components characteristics of Yongyou 6 and Boyou 253(CK) were studied.

Biological characters, yield components and grain filling characteristic were analyzed in four types of e-hybrids.

Based on the systematically measuring and generalizing the soil fertility conditions,yield component factor and yield spatial distribution of soybean 3 750 kg·hm~(-2)in different years in Xinjang Altay area,this paper presents the corresponding condition and high-efficient cultivation technique for soybean 3 750 kg·hm~(-2)in this area.
