7至9月是甘蔗伸长生长的黄金季节,这段天气处于高温强光,甘蔗长势旺盛,根系发达,吸收能力强,无论外因内因都具备了大生长的条件。在甘蔗伸长期,能充分满足它对条件的要求,就能使茎的每个节间充分伸长增粗,使蔗茎高大,故有蔗高全靠七、八、九之说,这一时期是决定单产高低的关健时刻,抓好田间管理夺取高产高糖,是获得较高的经济效益的基本保证。 一、合理灌溉 甘蔗是一种耗水量大的作物,水对甘蔗的生长快慢和产量高低有着密切的关系。大生长期的甘蔗叶面积指数高,叶面蒸腾量大,有机物的制造、运输、
From July to September is the golden season of sugarcane elongation and growth. During this period of high temperature and high light, sugarcane is growing vigorously with developed root system and strong absorptive capacity. Both internal and external factors have great growth conditions. In the cane elongation period, it can fully meet the requirements of its conditions, we can make the stem of each section fully extended thickening, so tall cane stem, so sugarcane high thanks to seven, eight, nine of that, this The time is a crucial moment for determining the level of yield. Grasping the field management to seize high-yield and high-sugar is the basic guarantee for obtaining higher economic benefits. First, rational irrigation Sugarcane is a water-intensive crops, water on the growth of sugarcane speed and the level of production is closely related. Large growing sugar cane leaf area index, leaf transpiration, organic matter manufacturing, transportation,
