1.炕种或晒种播前实行炕种或晒种,能降低种子含水量,促进种子内部转化。试验证明,炕种或晒种可使种子发芽率平均提高17％。同时,也能提高发芽势。2.作好发芽试验3月中旬,将各队的棉种,按种囤上、中、下各部位分别抽100粒,每队抽300粒。用细砂加表土做成播种床,在火炕上加温试芽,室内用煤炉助温。先将每百粒种子用65℃温水浸泡2小时,然后捞出分别播在床上,
1. The kang or sun-sown before the implementation of kang species or sun, can reduce the seed moisture content, and promote the transformation of the seeds inside. Experiments show that kang species or sunburn seed germination rate can be an average increase of 17%. At the same time, can also increase the germination potential. 2. Make germination test In mid-March, the cotton seeds of each team, according to the kind of store on the middle and lower parts were pumping 100 capsules, pumping 300 capsules per team. Made of fine sand and topsoil planting bed, heat test buds on the kang, indoor coal stove to help warm. First of each 100 seeds soaked in 65 ℃ warm water for 2 hours, then remove and sow in bed,
