吉林省谷子高产栽培技术研究

STUDIES ON HIGH YIELD CULTIVATION OF MILLET IN JILIN PROVINCE

摘要:

在前两报中对谷子个体生长发育规律和氮肥的适宜施用时期、数量及效果进行了讨论。第三、四、五报侧重研讨获得谷子高产在播期、密度、防倒伏方面应该采取的有效措施。即:改早播为晚播,在保墒条件下谷子最适宜的播期为4月末—5月初;在中等肥力条件下,中晚熟品种最适宜的密度为每亩4.5—5万株。中熟品种每亩为6.5万株;整地质量好的田块,每亩应播种0.4—0.5公斤。整地质量一般或稍差的田块,每亩应播种0.6—0.7公斤;播幅在12—15厘米为宜,肥地上选用中熟中穗型品种,用加大密度的方法控制单穗粒重、增加总粒重,是谷子防倒增收的有效途径。

Abstract:

Millet individual growth and the suitable time, the numbers, the effects of opplying nitrogen fertilizer properly have been discussed in the two preceding reports. The third report is to discuss the effective measures of sowing time, plant densities and preventing lodging for getting high yield of millet, that is, chan ging sowing date from early to late, the suitable sowing period is from the end of april to the begining of May Under the preservation of soil moisture. Under medium fertility the most suitable densities of medium-late maturity variety and medium maturity variety are 675, 000—750, 000 plants per hectare, and 950, 000 plant per hectare respectively. In the fields of good soil prepara-tion 6—7.5Kg of millet seeds should be sown per hectare. while 9—10Kg millet seeds should be sown per hectare in the fields of mediocre or less scil preparation.12—15cm sowing width within the row of millet is suitable. It is the effective ways to preven millet loding and to increase yield that the millet varieties of medium maturity-medium ear type are selected and the grain weight per ear is controlled, the total grain weight is increased by increasing of densitis in the rich soil.
