作物生产是人类利用光能的一种经济有效的手段。然而,人们对阳光能的利用率迄今仍很低。所以,提高光能利用以增加作物产量,是农业生产的根本任务。本文讨论甘蔗育苗移栽和麦菜间作菜收后植蔗,对提高甘蔗以及其他与甘蔗轮、间、套种作物的光能利用之效应。研究表明,育苗移栽的甘蔗其茎高增加15.6厘米,茎径增加0.159厘米,每公顷有效茎数多6420条,所以,原料蔗茎产量增加13.66％,每公顷含糖量增加7.314吨,光能利用率增加0.0990～0.3795％。每公顷育苗移栽的甘蔗,农民收入增加870元,国家的利润约增加3000元。研究也表明,采用麦莱间作菜收后植蔗的办法,小麦按实际播种面积计算,每公顷增加736.5公斤,增产率达25％。此外,每公顷增收蔬菜15吨。由于蔬菜比小麦早收获一个多月,甘蔗可早种,又不受其他作物荫蔽,所以,茎高增加6.7厘米,茎径增加0.05厘米,每公顷有效茎数增加21930条,每公顷原料蔗产量增加27.588吨,增产率为24.70％。另外,间作物大豆也可以早播,每公顷增产429.17公斤。光能利用率合计增加0.3932％,农民每公顷利润增加1260～1290元。上述两种措施已由福建省科委组织技术鉴定,证明经济效果显著。已在全国主要蔗区推广。
Crop production is a cost-effective means of human use of light energy. However, people’s utilization of sunlight is still low. Therefore, improving the utilization of light energy to increase crop yields is the fundamental task of agricultural production. This article discusses the effects of sugarcane seedling transplanting and planting and harvesting of sugarcane between crops on sugarcane and improving the utilization of light energy of sugarcane and other intercropping and intercropping crops. The results showed that the sugarcane transplanted seedlings increased 15.6 cm in stem height and increased 0.159 cm in stem diameter with 6420 effective stems per hectare. Therefore, the yield of sugarcane in raw material increased by 13.66% and the sugar content per hectare increased by 7.314 tons. Light Can increase the utilization rate of 0.0990 ~ 0.3795%. Per hectare of transplanting sugarcane seedlings, farmers income increased 870 yuan, the state’s profit increased by about 3,000 yuan. The study also shows that the method of harvesting and planting sugarcane with McLean is used to increase the yield of wheat by 736.5 kg per hectare and increase the yield by 25% according to the actual sown area. In addition, 15 tons of vegetables are added per hectare. As vegetables harvested more than a month earlier than wheat, sugarcane can be planted as soon as possible, and not covered by other crops, so stem height increased 6.7 cm, stem diameter increased 0.05 cm, the effective stalk per hectare increased 21930, yield of raw cane per hectare An increase of 27.588 tons and an increase rate of 24.70%. In addition, the inter-crop soybean can also be sown early, yielding 429.17 kg per hectare. The total utilization of light energy increased by 0.3932% and the profit per hectare of farmers increased by 1260-1290 yuan. The above two measures have been organized by the Fujian Provincial Science and Technology Commission technical appraisal, to prove that the economic effect is remarkable. Has been in the country’s main sugarcane area promotion.
