PRELIMINALY ANALYSIS ON PRODUCTIBILITY OF TILLERS IN PREMATURE RICE CUL TIVAR Ⅱ. THE PRODUCTIBILITY OF EACH KNOTTILLERS UNDER THE OVRE SPARSE PLANT

摘要:

在超稀植栽培条件下, 测定了早熟品种的分蘖生产力, 其结果表明, 在超稀植条件下, 不象密植栽培那样, 出现明显的优势分蘖节位, 在由营养生长转向生殖生长以前出现的分蘖, 其生产力基本相等。从而可以认为, 超稀植栽培有利于发挥早熟品种的分蘖生产力, 以此达到安全高产之目的。

Abstract:

Under the condition of over sparse planting, the productibility of tillers in premature cultivar was measured. The result indicated: under the over sparse planting condition, there are not any tillers superior to others, viz. unlike close planting. Before the vegetative growth turn into generation growth period, the productibility of al tillers are equal. Thus it could be considered that over sparse planting were advantageous to develop the productibility of tillers in premature cultivar and secure for high yield.
