The results were as follows.1 .Among three different kinds of forests, models that eggs, larvae and adults of Saperda Papulnea L. abided by varied, but they all showed spatial patterns of gregarions with variable extents.

结果表明： 1。在三种不同的林分中，青杨天牛卵、幼虫和成虫所拟合的模型不同，但均表现为不同程度的聚集型的空间格局。

Studies on spatial heteroplasmy of Saperda Papulnea L. population from different directions indicated that the model of semivariogram of eggs, larvae and adults in four directions are the same, but spatial dependent range are different, belonging to geometrical anisotropy. They had stronger continuity in the direction of 0° and 45° than the other two directions.

对不同方向上青杨天牛种群空间异质性研究表明：天牛卵、幼虫和成虫在四个方向上的半变异函数拟合的模型相同，但空间依赖范围却不同，属几何性的各向异性。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
