The results of the experiment were as follows.For anyone of the experimential varieties, the bigger the functional leaf area the longer the functional period the higher the 1000-grain weight. When wheat was sown at a proper time, functional leaf area increased, the functional period the became longer and the 1000grain weight rose. When wheat was sown ahead of time or late, the functional leaf area decreased, the functional period because shooter. Moreover the far the deviation from the proper sowing time, the bigger the decreasing range of the leaf area and the functional period, the lower the 1000-grain weight. Besides the leaf area decreased and the functional period shortened, but the 1000-grain weight increased as the basic seedling numbers increased. The leaf area increased but the 1000-grain weight was not certainly high by only increasing the amount of Nitrogen (N) fertilizer in the experiments. The leaf area decreased, but the 1000-grain weight increased by only applying Phosphate (P) fertilizer. The functional period became longer, and the 1000-grain weight rose by increasing suitable amount of N or P fertilizer. There was a remarkable effect for r aising the 1000-grain weight by mixing N with P fertilizers in the soil.

试验结果认为,在供试品种中,凡功能叶面积大、功能期长的品种,其千粒重也高;适时播种,功能叶面积增加,功能期延长,千粒重提高;提前播种或延迟播期,功能叶面积和功能期均有减少趋势,而且偏离适期越远,减少幅度越大,千粒重降低越明显;另外,功能叶面积和功能期亦随基本苗的增加而减少,千粒重则随基本苗的减少而增如;在试验范围内,单增施氮肥,叶面积增加显著,但千粒重并不高。单增施磷肥,叶面积还有减少趋势,但千粒重增加。追施适量的氮肥或磷肥,可使功能期延长,千粒重提高。实行氮磷配合施肥,对提高千粒重有显著的效果。

There were more than 133,000.hectares of wasteland and semi-wasteland along a long shore of jiangsu. The utilization of these land for the cultivation of herbage and establishment of artificial or semi-artificial pasture could play an imprtant role in developing animal husbandry of these regions. This paper presented the cultivation of forage plants for following several aspects. Firstly, the salinealkali soils must be improved with irrigati on of freshwater and cultivation of salt-tolerant plants. secondly, the selection of salt-tolerant herbage species, especially wild grasses,and introduetion of good ones. Thirdly, artificial or semi-artificial pastute of high yields and good forag qualities must be established on the basis of the Proper utilization of natural Pasture. It was emphasized that shallow ploughing, proper sowing time and increasement of sowing norm etc. could be adopted. Finally, there should be enough cultivation areas and a definite number of animals which transformed forage into animsl products to achieve a high economic effect.

江苏浜海地区土地资源丰富,在海堤内、外有荒地和半荒地面积在13.3万公顷以上。如能适当利用这部分土地,种植牧草、建立人工和半人工草地,必将对沿海地区畜牧业的发展起巨大的促进作用。本文着重叙述了江苏浜海地区种草的几个技术问题。种草必须从治碱改土人手,选择耐盐性强的植物和适生草种,扩大优良牧草的栽培面积,重视当地的野生草种,合理利用天然草地,建立人工和半人工草地。并根据浜海地区土壤的特点进行耕作管理,坚持浅层耕作,做到随耕、随耙、随种,适当加大播种量,注意排除积水等措施。同时,种草必须要有一定的面积,进而养畜、加工,做到草畜配套,才能提高种草的经齐效益。
