1985年我在四塘乡永靖村黄玉明家的新垦荒红土坡上对一亩八分西瓜进行了喷施0.05％浓度硝酸稀土与不喷稀土的对比试验。方法是幼苗期、开花期、座果期及幼瓜期各喷施一次,共三次。从试验结果表明:西瓜喷施稀土,对提高产量效果显著,每亩增产12.91—547.5公斤,增产幅度为14.3—60.5％。稀土对西瓜经济性状影响,主要表现是结瓜早、座瓜率高、甜度增加。据5月28日田间调查,喷稀土小区,每区平均结瓜47.6个,不喷稀土小区,每区平
In 1985 I was in the four village Yongjing Huang Yu Ming home reclamation red soil slopes on an acre of eight acres of watermelon were sprayed 0.05% concentration of rare earth nitrate and non-spraying rare earth comparative test. Method is the seedling stage, flowering, fruit stage and the young melon spray time, a total of three times. From the test results show that: watermelon spraying rare earth, to improve yield significantly, yield 12.91-547.5 kilograms per mu, increase rate of 14.3-60.5%. Rare earth on the economic traits of watermelon, the main performance is early fruiting, watermelon rate, sweetness increased. According to the field survey on May 28, spraying rare earth plot, the average area of 47.6 per pumpkin knot, do not spray rare earth plot, each district level
