大豆是需硼较多的作物。我省的大豆产区,土壤中的有效硼含量都比较低。据我地试验,大豆施硼后,一般可增产10％～20％,而每公顷大豆所需的硼肥费用还不到10元。大豆施硼有3种方式:喷施、底施和拌施。 底施 每200克硼砂对水1公斤,均匀喷到10公斤粉碎了的饼肥上进行堆沤,待饼肥腐熟后再与4公斤～5公斤尿素或5公斤磷酸二铵混匀,播种时与种子混匀再播。 拌种 每公顷用115克硼砂,对水3公斤,拌豆种75公斤,待种子变干后播种。 喷施 每公顷每次用750克硼砂,对水750公斤,在大豆第3片复叶期、花前7天～
Soybeans are crops that require more boron. Soybean producing areas in our province, the effective boron content in the soil is relatively low. According to my experiments, after the application of boron in soybeans, the yield can generally be increased by 10% to 20%, while the cost of boron fertilizer per hectare of soybeans is less than 10 yuan. Soybean boron has 3 ways: spraying, the end of Shi and Shi Shi. At the end of every 200 grams of borax on the water 1 kg, spray evenly sprayed on 10 kg crushed pie fat on the reactor, until the cake fat maturity and then with 4 kg to 5 kg of urea or 5 kg of ammonium dihydrogen phosphate mix, sowing and seed Mix and replay. Seed dressing with 115 grams per hectare of borax, 3 kg of water, mix beans 75 kg, until the seeds dried and sown. Spray per hectare with 750 grams of borax, 750 kg of water, in the first phase of soybean compound leaf period, 7 days before flowering ~
