春大豆移栽是提高大豆单产的一项有效措施。它的主要优点有三,一能保证季节,适时播种;二能避免鸟类为害;三能保证全苗,为高产奠定良好的基础。俗语说:“有钱买种,无钱买苗”,这句话充分说明了全苗的重要性。目前我区春大豆一般亩产停留在100～150斤左右的低水平。低产的主要原因之一是难以全苗,据调查,由于缺苗一般要减产10～35％。改直播为育苗移栽就能较好地解决这个问题,是提高春大豆单产的一项很有效的措施。1983春季,由于天气反常,阴雨低温持续的时间很长,除延误播种季节外,播后缺苗现象非常严重。我们调查了赣县、安远、南康、信丰等县的六个点,缺苗率达19.6～46.2％。
Spring soybean transplanting is to improve soybean yield is an effective measure. Its main advantages are three, one to ensure the season, timely sowing; two to avoid bird damage; three to ensure the whole plant, lay a good foundation for high yield. As the saying goes: “Rich money to buy a species, no money to buy seedlings,” This sentence fully illustrates the importance of whole seedlings. At present, the general area of spring soybean in our district stays at a low level of about 100-150 kg. One of the main reasons for low yield is difficult to seedlings, according to the survey, due to the lack of seedlings generally cut 10 to 35%. Change live broadcasts for transplanting seedlings will be able to better solve this problem is to improve spring soybean yield is a very effective measure. In the spring of 1983, due to the abnormal weather, the prolonged rainy and low temperatures continued for a long time. In addition to the delayed sowing season, the lack of seedling after sowing was very serious. We surveyed six counties in Gan County, Anyuan, Nankang and Xinfeng counties, with the rate of missing seedlings reaching 19.6 ~ 46.2%.
