据国内资料的报导,溴化钾,666浸拌种籽,均有刺激植物生长,提高产量和品质的作用。如保加利亚1952——1953年用溴化钾浸种,棉花增产10—12％。中国科学院和华北农科所用溴化钾浸种,棉花增产12——20％。为着明确溴化钾溶液以及666粉剂在南部棉区对浸拌棉种的影响,以及在生产上利用价值,我们在国营地方松滋农场,就当地栽培珂字棉布置对比试验,获得初步结果,简报如下。 一、方法 1、0.3％溴化钾溶液浸棉籽24小时,凉乾一天,即可播种。浸种时药液温度21℃用量是棉籽16份,药液1.5份(棉籽浸24小时,吸水率111％),如浸种多,药液可适当减少。 2、0.5％666粉剂,乾拌棉籽,用棉籽16份,666粉1份。
According to reports from domestic sources, potassium bromide and 666 soaked seed have the effect of stimulating plant growth and improving yield and quality. Such as Bulgaria 1952 - 1953 soaked with potassium bromide, cotton yield 10-12%. Chinese Academy of Sciences and North China Agricultural Potassium bromide soaked, cotton yield 12 - 20%. In order to clarify the impact of potassium bromide solution and 666 powder on the cotton seed soaked in cotton in the southern cotton area and the value of its utilization in production, we conducted preliminary tests on the comparison of local Cochine cultivation arrangements at the Songzi Farm in the local area The briefing is as follows. First, the method 1,0.3% potassium bromide solution soaked cotton seed 24 hours, dry one day, you can sow. Soaking liquid temperature 21 ℃ dosage is 16 parts cottonseed, liquid 1.5 (cottonseed soaking 24 hours, water absorption 111%), such as soaking, the liquid can be properly reduced. 2,0.5% 666 powder, dry cottonseed, with 16 parts of cottonseed, 1 666 powder.
