日光温室白皮黄瓜配方施肥研究

应用“目标产量法”对日光温室白皮黄瓜进行配方施肥研究,日光温室白皮黄瓜产量93.88 t/hm2,计算优化的肥料配方(以667 m2量计算)：基施有机肥5 000 kg+过磷酸钙77.16 kg+尿素12.16 kg+硫酸钾15.30 kg,于根瓜实膨大期、盛瓜初期和结瓜盛期分3次进行追肥,每次追施尿素8.12 kg、硫酸钾10.21 kg。通过大田试验,配方施肥区植株生长势强,比对照增产21.06 %;每667 m2节约尿素13.48 kg、过磷酸钙22.84 kg、硫酸钾14.07 kg。

Application of Fertilizers to White Cucumber in Greenhouse

According to "goal yield method", we studied the application of fertilizers when we plant white cucumbers in greenhouse. The results showed that: In order to obtain 93.88 t/hm2 white cucumbers, at first, organic fertilize 5 000 kg+calcium superphosphate 77.16 kg+urea 12.16 kg+potassium sulphate 15.30 kg should be fertilized before planting in 667 m2, then urea 8.12 kg+potassium sulphate 10.21 kg should be fertilized during the root fruit enlargement period, the prosperous period and the early full fruit period separately. And if so, plant can grow better, white cucumbers can be achieved significant yields being 26.1 %, and urea 13.48 kg+calcium superphosphate 22.84 kg+potassium sulphate 14.07 kg can also be saved in 667 m2.
