It is meaningful to provide technique support for integrated disease control by exploring the effective control measures of wheat stripe rust. Wheat stripe rust dynamic developments of all-planting and mixed-planting have been systematically investigated in this study by taking different mixed-planting combinations among 6 wheat varieties with different resistance levels. The results of this experiment show that the mixed-plantings of 4 and 6 wheat varieties can delay the occurance of wheat stripe rust,slow the speed of disease and decline the damage of disease as well as stabilize yield of wheats.展开更多

It performs well in yielding, lodging resistance, disease resistance, with a short duration of growth. Therefore, it is suitable to be grown in tropical areas and countries such as Myanmar and Indonesia. The male parent contains herbicide susceptible lethality gene and it is possible for mechanical mixed planting. The research analyzed performance of Hunyou No. 2 growth in Myanmar and the results showed that Hunyou No. 2 performed better in yield, panicle length, the number of seed per panicle, setting percentage, and thousand-seed weight than She thwe yin, as well as lodging resistance, disease resistance and quality. Some high-yielding cultivation measures have been concluded including sparsely sowing, densely planting, highlighting base fertilizers, and avoiding early water breaking.展开更多

This study was aimed to verify the weeding-effect on dry matter （DM） production in the farm level and to examine the effect of several weed control, i.e. mixed sowing of annual setaria （abbreviated as S）, which has no regrowth ability after stem-elongation, paper-mulching （as P） and hand-weeding （as ＋W）, compared with no-weeding （as -W） on DM yield and quality of DL napiergrass in two years. Weed control practices significantly （P 〈 0.05） promoted several plant growth attributes in DL napiergrass, compared with no-weeding both in the farm and experimental levels. Paper-mulchidng （P-W or P＋S-W） had highest yields among several practices in both years. Setaria-sowing ha a partially mitigating effect of weed damage on DM production of DL napiergrass, while additive DM gain from setaria could compensate the yield decrease in DL napiergrass and reduce herbicide cost. Neither digestibility nor crude protein was affected by any weed control in either year. Thus, paper-mulching and annual setaria-sowing could be effective alternative practices for weed control of this species.展开更多
