Persicum when seeds were submerged in 700 mmol.L-1 NaCl solution, especially for recovery germination and total germination when ungerminated seeds were air-dried and then transferred to distilled water, while these were increased markedly when seeds were submerged and aerated in 700 mmol.L-1 NaCl in H.

Salt tolerance of 10 alfalf varieties during geminating period has been studied by measuring germination rate, the germinating energy, seedling weight and seedling height under the treatments with 0% 0.3% 0.7% and 1.0% NaCl solution respectively.

对10个紫花苜蓿品种种子分别用0%、0.3%、0.7%和1.0%的NaCl溶液进行处理,通过种子发芽率、相对发芽势、幼苗重和幼苗高对各品种种子萌发期耐盐性进行了研究。

If we reflected carefully about life. For example: the small green fruit of apricot grows after its flower withers and the beautiful red color diminished. Most people feel depressed and sick, but actually when the fruit grows up and gestates seeds that are the starts of many new lives. Seeds germinate and grow many new flowers which are delicate and beautiful will display before us again, aren't they?

When the mevinphos was utilized for a long time in highland barley field, the young-root of next-season cole shortened 1.9~2.0cm and fresh weight decreased 0.13~0.14g per individual plant compared with the control. Low-tillage in time after autumn-harvest showed that the weed seeds in the ground surface were harrowed into the tilth of 0~10cm. Early-low-tillage in spring-sow of the next year induced weed seeds of soil surface to germinate and come out ahead. After 10 days, tillage-sow can decrease about 40% weeds. Compared to the normal plough-row, direct late-tillage-row was postponed 10 days, and can decrease about 30% weeds. In the seedling period or later, rudimental weed seeds were handled with a hoe, which led to better cure and control effects and had more benefits to the young seedling growth and yield of the next-season crop.

研究结果表明:氟乐灵在油菜田长期使用时,土壤残留农药抑制下茬青稞幼根生长,幼根较对照株缩短3.0~3.1cm/株,鲜重量减少0.19~0.20g/株;甲磺隆在青稞田长期使用时,下茬油菜幼根较对照株缩短1.9~2.0cm/株,鲜重量减少0.13~0.14g/株;秋收后及时浅耕可将落入地表的杂草种子全耙入0~10cm耕层内;翌年春播早浅耕可诱发土壤表层的杂草种子提前萌发出苗,10d后耕种,能防除40%左右的杂草株数;较正常播种期推迟10d后直接晚耕播种,可防除30%左右杂草株数;苗期或后期拔出残余杂草种子时,除草效果理想,对下茬作物幼苗生长发育及产量无任何不良影响。
