种于生长室内的野燕麦,经过一个最初停滞期以后,干物质积累迅速增加,直到出苗后八周。在出苗后六周株高及每株叶片数的增长率几乎呈一直线。分蘗主要发生在出苗后的2—4周。低光强度及短光照严重阻碍生长,且延迟抽穗和成熟。虽然在较高的温度下(28—20℃)最初生长较快,但以昼—夜温度20—12℃时植株生长最好。在黑壤土内,只是在高光强度下,植株才对增施氮和磷有反应。土壤湿度和 PH 都对野燕麦的生长有较大的影响。在土壤 PH 为7.5或8.5、土壤湿度为田间持水量75%以上时,干物质积累量最大。种子外壳颜色对野燕麦植株的生长没有影响。大粒种子长出的植株比小粒种子长出的植株干重高一些。就这些结果对野燕麦的防治进行了讨论。
Wild oats planted in the growth chamber, after an initial period of stagnation, rapidly increased dry matter accumulation until eight weeks after emergence. At six weeks after emergence, the plant height and the number of leaves per plant increased almost linearly. Tillering occurs predominantly 2-4 weeks after emergence. Low light intensity and short light severely hampered growth, and delayed heading and maturation. Although the initial growth was faster at higher temperatures (28-20 ° C), the plants grew best at day-night temperatures of 20-12 ° C. In black loam soil, plants respond to increased N and P only at high light intensity. Soil moisture and pH have a greater impact on the growth of wild oats. In the soil PH is 7.5 or 8.5, the soil moisture is more than 75% of field capacity, the accumulation of dry matter the largest. Seed shell color has no effect on the growth of wild oat plants. Large grain seeds grow more dry weight than plants grown from small seeds. The results of the prevention and treatment of wild oats were discussed.
