一播保全苗是棉花早发、丰产的基础。由于干旱、盐碱、低温、病菌危害等不利因素的影响,常常不能如愿。为寻找有效的保苗措施,我们对河北省农科院土肥所研究成功的棉花种子处理剂——棉花保苗剂,进行了田间试验。试验地设在我县大王庄村农民张秋鳔的棉田。供试棉花品种为182,播期为4月24日,播种方法为耧播,亩下种量4公斤,设对照和浸种两个处理,三次重复。底施碳铵折亩施纯氮7公斤,亩施普钙磷肥拆 P_2O_5 5公斤,并于5月4日锄梦花一次,其试验结果如下:
A broadcast security seedlings is cotton early, high yield basis. Due to drought, salinity, low temperature, harmful bacteria and other unfavorable factors, often can not do so. In order to find effective seedling protection measures, we conducted a field experiment on the cotton seed treatment agent - cotton seedling agent successfully researched by soil and fertilizers of Hebei Academy of Agricultural Sciences. Experimentally located in the county Wangzhuang Zhuang village farmer Zhang autumn cotton field. Test varieties for the 182 cotton, sowing date April 24, sowing methods for sowing, mu under the 4 kg seed volume, set control and soaking two treatments, three replicates. At the bottom of the ammonium bicarbonate Shu Shi 7 kg of pure nitrogen, Muxipu calcium phosphate demolition P_2O_5 5 kg, and on May 4 hoe dream flower, the test results are as follows:
