In the forth chapter, the mechanism of pyrimidine benzylamine compounds is studied by the conventional bioassay and biochemical methods based on probe compound 104-4. The results presented here indicated that the addition of 5 mg/L of 3 branched-amino acids to sorghum seedling cultures incubated in the presence of 104-4 completely alleviated herbicide-induced stem growth inhibition, but each of Val, Ile and Leu single is only partly effective in reversing 104-4-induced growth inhibition at the same concentrations.

The pyrimidine lead compound is obtained via herbicidal activity screen. The optimization of lead compound leads to find the good pyrimidine benzylamine candidates with highly effective herbicidal activity. The novel herbicidal mechanism of pyrimidine benzylamine is put forward. N-(2-bromophenyl)-2-(4, 6-dimethoxypyrimidin-2-yloxy)benzylamine (103-1) has potential as a new selective post-emergent herbicide in oilseed rape.

The main achievements of the project are as follows: 1 the hypothesis that a decrease in seed mass causes an increase in mean dispersal distance has been tested based on the experiments of weed dispersal by wind. The experimental results partly support the hypothesis. The results will help farmers to make an optimal strategy of weed control; 2 a statistic method for inferring probabilistic distribution function of a random variable has been developed, by which probabilistic distribution functions of weed species dispersal have been determined; 3 the reproduction structure of Bromus sterilis has been studied; 4 a more complex CA model with 25 neighborhood cells were built, which can simulate spread of a weed population. This work promotes developments in both theory and application of CA models; 5 the "mean law" in weed control has been proposed. Accordingly, the algorism of patch spring may be calibrated; 6 the "patch" and "true patch" have been mathematically defined so that herbicide can be efficiently applied; 7 simulation validates that initial configurations of weed will affect dispersal of its population and strategies of controlling it, or its distribution patterns affect its dispersal progresses.

主要完成的工作和取得的成果有：1）用实验证实了重量较轻的杂草种子并不一定飞得比较重的远，其结果有助于农民制订杂草的优化控制策略；2）发展了一种推断随机变量分布函数的统计方法并用它来获得了几个杂草种的扩散分布函数；3）对杂草Bromus sterilis的繁殖结构进行了研究；4）建立了一个具有25邻的较复杂的能模拟杂草扩散的CA模型，并在理论和应用方面促进了CA模型的发展；5）在杂草控制方面提出了&平均法则&，据此可对按块施药方法进行校正；6）精确地定义了&块&和&真块&以便在杂草控制中能更有效地使用除草剂；7）模拟证实杂草种群的初始配置影响其扩散和控制策略，或者格局影响过程。

For over a hundred years,Rothschild family made strides forward through research for excellence and the gradual addition of a new technical team.In the vineyard,the replanting and restoration work was mirrored by reevaluated fertilizing and limited herbicide treatment.In the chais,a stainless steel tank complex was installed alongside oak tanks,and a new circular aging chain was constructed under the supervision of Catalan architect Ricardo Bofill.
