The testing result shows that there is a difference actual seed dropping angle and the one acquired by calculation, therefore, a formula for the calculation of seed dropping angle even closely suited to production practice has been driven out and a theoretical basis for the application of 2BQM-2 model plastic film mulch pneumatic precision planter in practical production is advanced in this paper.

通过试验结果分析，找出种子的实际的落种角度和计算的落种角度之间的差别，推导出更适合实际生产中所需要的落种角度，为2BQM-2型气吸式精量铺膜播种机在实际生产中的应用提供了一定的理论基础。

Aiming at the problem that the seeds picked up by the suction plate of the seed metering device cannot accurately fall into the seed pit opener as well as into the seed pit, an innovated seed metering device on which the seed dropping angle can be adjusted within a certain range and a new testing stand have been developed in accordance with the mathematical calculation model that had 'in accordance with the mathematical calculation model that had been established previously.

本论文根据2BQM-2型气吸式精量铺膜播种机的结构和工作原理，针对该机在实际播种中，吸种盘吸出的种子不能满足准确地落入在膜上滚动开穴的鸭嘴内，并及时地排入到鸭嘴所成的穴孔内的设计要求，进行了一定的试验研究，利用已建立的计算数学模型，设计新的试验台，改进排种器，使排种器的落种角度可以在一定的范围内调整。

The second source of his optimism is the global boom in agriculture, which is leading to record demand for Deere's products, including combine harvesters, balers and seeders, as well as tractors.

他态度乐观的另一个缘由是全球农业的繁荣，这引发了对包括联合收割机、压捆机、播种机以及拖拉机等迪尔产品的空前需求。

A fertilizer leak-preventing device is developed to stop fertilizer leakageon the stirring-knife-reel adjusting fertilizer distributor,especially severe when operatedwith granulated fertilizers such as urea during the non-working state of the distributor.

针对使用搅刀－拨轮式排肥器的悬挂施肥播种机在施尿素等颗粒状肥料时，非工作状态所发生的肥料严重漏失问题，研究设计了阻止漏肥装置。
