馬鈴薯芽栽的經济意义 馬鈴薯芽栽,是一种多快好省的农业技术措施。首先,芽栽可以提高单位面积产量。据1959年丽水县农业科学研究所云和試驗埸試驗,芽栽的亩产可达4,252斤,比块栽的亩产3,275斤高出29.8％。其次,可以节省种薯。以往用块栽法,耗种薯多,随着密植程度的提高,种薯需要数量更多。而且大量的种薯在貯藏过程中,又容易因管理不善招致烂种等損失。根据試驗,采用芽栽时留种量至少可減少75％以上,如种芽育得好,掰芽后又将种薯进行切块播种,則省种更多,种薯利用率可提高5～7倍。試驗証明,掰芽后的薯块,还留有部分短芽,用来块栽,对产量并无影响或者影响极微。第三,馬鈴薯芽栽,还可避免因种薯带病,传染植株而影响产量。如馬鈴薯晚疫病主要是种薯带病传播的,由于将种薯上的芽掰下来栽压,病毒尚未侵入幼苗,因此可以避免晚疫病为害。
The economic significance of potato budding Potato budding, is a kind of more rapid and economical agricultural technology measures. First of all, bud planting can increase yield per unit area. According to the 1959 Lishui County Institute of Agricultural Science cloud and test 埸 test, bud planted up to 4,252 pounds per mu, planted acres of 3,275 pounds higher than the 29.8%. Second, you can save seed. In the past with the block planting method, consumption of potato and more, with the close planting degree, the need for more seed. And a large number of seed in the storage process, but also easily lead to bad management due to poor management and other losses. According to the test, when using bud planted to reduce the amount of seedlings can be reduced at least 75%, such as seed budding is good, after breaking the bud seed and then diced sowing, the more provincial species, potato utilization can be increased by 5 ~ 7 times. Test proved that after breaking bud potato block, but also part of the short bud left for planting, no effect on the yield or minimal impact. Third, the potato sprout planted, but also to avoid due to potato disease, infecting plants and affect the yield. Such as potato late blight is mainly spread of potato disease, due to the seeds on the shoot off the planter pressure, the virus has not yet invaded seedlings, it can prevent late blight damage.
