With exception of soils that are cold and wet at planting time , no evidence exists that surface broadcasting of potassium fertilizer is not an adequate method of fertilization under reduced tillage 除非在播种时土壤寒冷潮湿,没有证据表明在少耕制下钾肥地表撒施是一种不适当的方法。
Accordingly i dug up a piece of ground as well as i could with my wooden spade , and dividing it into two parts , i sow d my grain ; but as i was sowing , it casually occur d to my thoughts , that i would not sow it all at first , because i did not know when was the proper time for it ; so i sow d about two thirds of the seed , leaving about a handful of each 于是,我用木铲把一块地挖松,并把这块地分成两部分播种。在播种时,我忽然想到,不能把全部种子播下去,因为我尚未弄清楚什么时候最适宜下种。这样,我播下了三分之二的种子,每样都留了一点下来。
When seeding , this system automatically regulates the speed of the seed - sowing device according as the demand of sow quantity and the speed of the seeder . this speed is acquired by sensor . the land wheel skid and rough ground will influence the quality of seeding , then , by using this system the influence may be decreased 此系统在播种时,可以连续采集五轮仪的转速,并根据五轮仪的转速和作物播量要求调整排种器的转速;系统可以减小地轮打滑及地面不平对播种质量的影响,从而达到精量播种的要求。
