沙井子试验站今年共种植108—埃夫棉花236.71亩,平均亩产籽棉707.52斤,其中有29.5亩达到千斤以上.1.4亩单产籽棉1,415.84斤.根据今年栽植的情况,提出如下几点经验:(一)根据各地段不同的情况,分别及时采取不同的技术措施.我站棉田的情况不同,因此必须给予不同的措施.如早春在盐分较轻的地块,完全采用耙地;盐分较重的地块,就进行春灌治碱,然后春耕.对土壤瘠薄的地块,施加基肥;较肥的地块,则少施或不施基肥.在生长期的追肥,亦采取相同的办法,同时还注意了在氮肥多的地块增施磷肥,以调剂氮磷的配合比例.生长期的灌溉亦根据各地区的士壤湿度分别对待.如春灌的棉
Shajing sub-test station this year planted a total of 108-Eff cotton 236.71 acres, an average of 707.52 kg per mu of seed cotton, of which 29.5 acres reached more than 1000 pounds .1.4 acres of seed cotton yield 1,415.84 kg. According to planted this year, made the following experience: A) According to the different circumstances of each section, take different technical measures in time.My cotton fields in our station are different, so we must give different measures.If early spring in the salt is lighter land, completely harrow; salt heavier The plots were spring-seasoned with alkali and then plowed with spring. The basal soils were soiled with basal soils, and the more fertile plots were less or no basal fertilizers. The same applies to top-dressing during the growing season Attention should be given to the application of phosphate fertilizers in plots with large amounts of nitrogen to adjust the mix proportion of nitrogen and phosphorus, and the irrigation in the growing season is also treated separately according to the lettuce moisture in each region.
