| 摘 要： | 对青海环湖区浅、深耕农田收割后落入土壤中杂草(野燕麦、黎)种子量及分布进行了调查，并分别对浅、深耕田春灌用水、播前土壤水分含量进行了测定。结果表明：收割后及时浅耕能将当年产生的杂草种子全部耙入0～10cm的土层中，通过配施除草剂，对杂草的防除效果较好；浅耕田较深耕田春灌节约用水37．5％。

| Abstract: | The quantity of weed seed (Avena fatua L.,Chenopodium album L.)distributed in different soil layer by shallow and deep tillage are surveyed,the volume of spring irrigating water and the soil moisture before planting in shallow and deep tillage fields are investigated too.The result showed that timely tillage can put all weeds seed(produced by this year)into 0-10 cm soil layer,it benefit to weed control by utilizing herbicide.Shallow tillage fields can decrease the volume of irrigating water by 37.5%. |
