Abstract : the investigation of summer migration of rice water weevil lissorhoptrus oryzophilus kuschel in double cropping rice area of zhejiang province in 1994 and 1995 indicated that the main cause of its always low population density in second generation is that most of the adults of first generation emigrated from early rice fields for summer and winter hibernation
文摘:研究表明，浙江省雙季稻區稻水象甲二代蟲量低的首要原因是絕大部分一代成蟲遷出早稻田夏蟄並越冬，構成二代蟲源的比例極微。 -
The testing results of straw cutting and field experiment show that this mechanism has excellent anti - blocking capability. ( 2 ) a new no - till planter equipped with the strip chopping anti - blocking mechanism was developed. compared with other no - till planters, it possesses higher anti - blocking capability and suits the need of seeding in huabei plain where the winter wheat - summer corn continuous double cropping system gives much straw and short planting season
（ 2 ）研製出新一代玉米免耕播種機，配以新型防堵機構，防堵性能優越，連續三年分別對三代樣機進行的田間試驗表明，可在地表整稈覆蓋量10t / ha的條件下連續作業而不堵塞，該播種機的防堵性能好。 -

In this thesis, a new strip chopping anti - blocking mechanism and a new no - till planter operating well in heavy straw mulching condition are developed from the following aspects : ( 1 ) in order to solve the problem that the no - till planters can not work well when the mulched straw is long and thick, especially in the double cropping area of huabei plain where the winter wheat gives a high yield, a new strip chopping anti - blocking mechanism was developed. it consists of a group of rotary blades, a narrow tine opener, a shear bar, a hood and a deflector
在以下幾個方面進行了較為深入的研究： （ 1 ）在對國內外免耕播種機防堵裝置研究的基礎上，針對華北一年兩熟地區麥收后地表覆蓋量大的特點，通過對驅動式和從動式防堵裝置的對比實驗，設計出一種具有高效防堵能力的帶狀粉碎防堵裝置，該裝置由組合刀片、開溝器、定刀片、罩殼和導草扳組成。 -
Abstract : the climatic factors in different growth stages of late - seeded and filmed winter wheat were discussed with the application of the field test data. the agricultural climate cause of late - seeded and filmed winter wheat with high yield and water - saving was analysed. the species of late - seeded and filmed winter wheat corresponding to multi - cropping cotton was selected
文摘:根據田間試驗資料，討論了晚播膜下條播冬麥各生長發育時段氣候條件的適宜程度，並分析了晚播地膜冬麥高產節水的農業氣候原因，在此基礎上確定了與復播棉花相配套的晚播地膜冬麥的品種選擇。
