不同方式处理对提那罗爪哇大豆生长及种子产量的影响

以提那罗爪哇大豆为材料,研究不同种植密度、底肥、追肥、灌水次数对提那罗爪哇大豆生长、草产量及种子产量的影响。结果表明:(1)种植密度1.0 m×1.0 m处理,生长量最大,主蔓长205.33 cm,但草产量最低;种植密度0.5 m×1.0 m处理,产量最高,为1 074.84 kg/hm~2。(2)2个磷肥水平处理生长量、草产量和种子产量均高于未施磷水平。磷肥水平1 kg/102处理,主蔓长208.00 cm,一级分枝数25.33枝/株,草产量2 724.53kg/hm~2,种子产量最高,为1 022.99 kg/hm~2。(3)每株追施尿素6 g水平处理,生长量显著高于其它2个处理,主蔓长193.67 cm,一级分枝数22.67枝/株,且草产量比其它2个处理高,为2 690.20 kg/hm~2;每株施尿素3 g处理,种子产量比其它2个处理高,为824.71 kg/hm~2;(4)15 d灌溉1次水处理,生长量和种子产量均高于其它2个处理,主蔓长166.67 cm,一级分枝数21.00枝/株,种子产量1 050.62 kg/hm~2。

Effects of Different Treatment on Growth and Seed Yield of Glycine wightii Verdcourt cv. Tinaroo

Glycine wightii (Wight and Arn.) Verdcourt cv. Tinaroo is selected to research the effects of different planting densities, base fertilizers, topdressings and irrigation times on its growth, yield of seed and pasture. The results showed that the maximum growth occurred when the planting density is 1.0 m× 1.0 m, when its main vine's length is 205.33 m, the yield of pasture is lowest. The highest yield reached 1 074.84 kg/hm2 when the the planting density is 0.5 m ×1.0 m. The Phosphate level is 1 kg/102, the planting crop's main vine length is 208.00 cm, the first level branches is 25.33. The yield of pasture and seed are highest———2 724.53 kg/hm2 and 1 022.99 kg/hm2. The growth is significant higher than the other two treatments when 6 g urea/each, the main vine length is 193.67 cm and the first level branches is 22.67 branch per plant. The yield of pasture's seed is higher than the other two treatments when 3 g urea/each, it is 824.71 kg/hm2. The yield of pasture is higher than the other two treatments when 6 g urea/each, it is 2 690.20 kg/hm2. Both growth and seed yield of the crops which irrigated every 15 days are higher than other two treatments. The main vine length is 166.67 cm, the first level branches is 21.00 and seed yield is 1 050.62 kg/hm2.
