田菁由南方引入我区种植后,证明它是抗碱、耐涝、产草量高的优良绿肥作物。很受群众欢迎。但是,田菁留种问题在我省多数引种地区还缺乏经验。为了解决这个问题,以便扩大田菁种植面积,从1962年以来,我所进行了这方面的试验和调查研究。结果证明,采取有效的综合措施,完全可以获得产量高、质量好的田菁种子。我所1962年亩产田菁种75斤,发芽率40%,千粒重8.7克;1963年亩产125.8斤,千粒重12.8克,发芽率68.6%;1964年亩产最高达217斤。据我们两年来在德州、乐陵、济阳等地田菁留种成功的生产队调查,亩产种子也在百斤左右,最高的能收200余斤。
After introduced into our district by the South, Tian Jing proved that it is an excellent green manure crop that is resistant to alkali, waterlogging and high grass yield. Very popular with the masses. However, Tian Jing remaining problems in most of the introduction of the province is also lack of experience. In order to solve this problem so as to expand the planting area of Sesbania, I have carried out experiments and investigations in this field since 1962. The results show that the adoption of effective integrated measures, can get high yield, good quality Sesbania seeds. In 1962, we produced 75 kg of field jungle seed with a germination rate of 40% and a grain weight of 8.7 grams. In 1963, 125.8 kg of grain per mu, 12.8 grams of grain weight, and 68.6% of germination rate. The highest yield was 217 kg in 1964. According to our two years in Texas, Leling, Jiyang and other fields Tianjing success of the production team investigation, per mu seeds are also about hundred pounds, the highest can receive more than 200 pounds.
