海拔2800m的山区地膜春小麦试验研究

2006年，在海拔2800m以上的和田县喀什塔什乡科克阿依村进行地膜穴播春小麦与露地春小麦栽培对比试验。地膜覆盖技术改善了小麦生物性状，分蘖数和成穗率大大提高，千粒重也有所增加。除4月15日播种的外，株高、结实小穗数、穗粒数都比露地播种小麦增加，A、B、C三处理比对照籽粒产量分别增加75．5％、82．0％和52.3％，增产效果非常明显。能有效解决低温半干旱山区春小麦生产中存在的粗、旱、冻等突出问题，具有较好的保墒蓄水、增温保温效能，有明显的增产增收作用，是小麦生产再上台阶的一项有力措施，值得在南疆海拔2800m以上的山区大力推广应用。

Experiment on Spring Wheat Mulched with Plastic Film in 2800m Mountain Areas

A contrast experiment between the film hole sowing spring wheat and the open field cultivation of spring wheat was carried out at Kekeayi Kashitashi Village in Hetian county, located altitude 2800m upwards in 2006. The plastic mulching film （hole sowing） technique improved the biological traits of wheat, enhanced greatly the numbers of tiller and the rate of earring, and 1000- grain weight has increased. The plant height, the numbers of seed setting spikelet and ear particle were increased than the same of the open field cultivation of spring wheat. Three treatments of A, B, C were increased 75.5%, 82.0% and 52.3% than the contradistinguished grain yield respectively. The result of boost yield was very obvious. The plastic mulching film （hole sowing） technique can effectively solve the coarse, dry, frozen and other outstanding problems which existed the mountain areas of semi-arid and low-temperature, and to have a better efficiency about preserving soil moisture and storage water, warming and heat preservation. It has a distinct effect for increasing production, and to be a powerful measure for wheat production to go to a higher level. It will be worthwhile on application and extension in the mountain areas of southern Xinjiang.
