当前我省红麻产量较低,主要原因是缺苗。为确保苗全苗壮,要抓好以下几个环节。 1.做好发芽试验。根据发芽率确定播种量。发芽率在70％以上时,每亩播3.5～4.5斤。 2.看墒情和地温确定播期。当5厘米地温稳定在12℃左右,土壤水分不低于16％时(4月25～5月25日)为播种适期。 3.提高播种质量。播种时要加宽播幅,开沟要直,深浅一致,下种要匀。踩格子要严,覆土厚度1寸左右。播种后要根据土壤墒情、性质压1～2遍木头磙子。
The current low yield of kenaf in our province, the main reason is the lack of seedlings. In order to ensure the seedlings are strong, we must grasp the following aspects. 1. Sprout test done. Determine the sowing rate according to the germination rate. Germination rate of 70% or more, sowing 3.5 ~ 4.5 pounds per mu. 2. To see the moisture content and temperature to determine sowing date. When 5 centimeters of geothermal stability at about 12 ℃, soil moisture of not less than 16% (April 25 ~ May 25) for the sowing period. 3. Improve the quality of planting. Seeding should be widened broadcast width, ditching should be straight, the same depth, the next species to be uniform. Step on the grid to be strict, soil thickness of about 1 inch. After sowing soil moisture according to the nature of 1 to 2 times the pressure of wood prickly heat.
