硼素是棉花生育中必需的一种微量营养元素。我区试验研究与大面积施硼实践结果表明,一般棉田喷硼2至3次,棉花增产15％左右。1984年全区棉田喷硼面积达60多万亩,占植棉面积的30％以上。因此,推广棉田喷硼技术是一项施用安全(无毒害)、投资少(每亩4至6角)、效益大(一般亩增产15斤皮棉、增收20元)的经济植棉措施。
Boron is a necessary micronutrient in cotton growth. The results of pilot study and large-area application of boron in our area show that the average cotton field sprays boron 2-3 times and cotton yields about 15%. In 1984, the area of boron sprayed cotton in the whole area reached over 600,000 mu, accounting for more than 30% of the area of cotton planting. Therefore, the promotion of cotton spraying technology in cotton field is an economic cotton-planting measures with safe application (no poison), low investment (4 to 6 per acre), large benefit (increase of 15 kg of lint per mu and increase of 20 yuan).
