As the track space increasing, the holding power which flexible holding parts act on sugarcane is dropping off. As the canvas layers and length of flexible holding part increasing, the track space is also increased when flexible holding parts act on sugarcane same holding power. As the length of flexible holding part increasing, the rate of slope of holding power following the track space to change would be decreased, so holding power would vary slowly. The holding power has a better linear relationship with the track space. Holding sugarcane stalk on knot or not on knot, sugarcane stalk having leaves or without leaves, the holding power would have not significant difference. Considering the structure of device and stress of sugarcane, 4-layers canvas conveyer belt was used as flexible holding part, while its length is 120mm, 160mm, or 200mm, the corresponding maximum track space is 135mm, 183mm, or 235mm. Experimental investigation of sugarcane windrowing was done on the arc-track-type flexible holding and conveying test mechanism.

随着轨道间距的增大，柔性夹持元件施加给甘蔗的夹持力逐渐减少；施加给甘蔗相同的夹持力，随着柔性夹持元件帆布帘层数和长度的增加，对应的轨道间距增加；随着柔性夹持元件长度的增大，柔性夹持元件施加给甘蔗的夹持力随轨道间距变化的斜率减小，夹持力大小的变化越缓慢；柔性夹持元件提供的夹持力与轨道间距均呈线性关系；柔性夹持元件夹在甘蔗节上还是不夹在节上，甘蔗有叶还是无叶，其施加给甘蔗的夹持力无显著差异；从夹持输送装置结构以及甘蔗的受力情况来考虑，选择4层帆布帘输送带作为柔性夹持元件更能平稳、柔和地夹持输送甘蔗，4层帆布帘120mm、160mm、200mm长的柔性夹持元件夹持甘蔗所需最大轨道间距为135mm 、183mm、235mm。

Since curly leaf hybrid could be recognized at early stage,and displayedobvious dwarfness,choosing"Zha′ai 76"as paternal parent not only raised thehybrid-selecting efficiency from the pollinated progenies,but also raised thebreeding efficiency of apomctc dwarf roostock of apple.

鉴别宽叶型杂种较难、需时较长(2-3年生时)并需与染色体倍性鉴定法相结合，因其形态变化较小而生长势又与平邑甜茶无融合生殖苗无明显差异；鉴别光叶型杂种因父本染色体组的影响加大而从形态上容易些，但也需过氧化物同工酶法或染色体倍性鉴定法相配合；皱叶型杂种因在苗期刚出1-2片真叶时就表现明显的标志性状、能从叶片形态上准确鉴别出来，毋须染色体倍性鉴定等复杂方法；因皱叶型杂种能早期鉴别，又表现明显的矮生性，因而选用"扎矮76"做父本不仅大大提高了平邑甜茶授粉后代中选择杂种的效率，而且提高了苹果无融合生殖型实生矮砧育种的效率。

The response may change the fate of the turions in the second year,and affect the maintenance of the populations.

在野外池塘中，利用3种不同营养状况的底质研究底质营养盐对菹草生长及养分分配的影响，结果表明：沉水植物菹草面对底质营养盐的胁迫出现了急性的生理生化反应，在生长初期叶片总的可溶性糖含量在肥沃的底质上高于贫营养底质上；根、茎、叶和石芽各构件都具有异速生长现象，并且表现规律不一样；菹草的根冠比随底质营养盐的不同而变化；随着营养条件对菹草生长胁迫加重，根、冠的异速生长愈明显，同时石芽的N∶P和C∶N比率显著受底质营养盐的影响，而菹草叶片和茎N∶P和C∶N比率不受底质肥力的影响，这些响应将改变石芽第2年的命运和影响种群的维持；在胁迫生境下，菹草首先分配资源到无性繁殖体--石芽上以便维持种群的延续，以回避策略应对底质营养盐胁迫。
