Suizhong County Songliu commune six brigade three teams of scientific research team in 1977, corn in red paddy rice and dryland paddy rice in the trial after the successful drip irrigation, rape this year in the flowering stage, wheat heading stage and greenhouse film dry nursery seedlings made Drip irrigation test, the effect is significant, are summarized as follows: First, the drip irrigation effect of rape bolting flowering stage 1. Test Method: The test soil is sandy soil, soil thickness of about 1 municipality, an area of 0.3 acres, zoned for two districts to 0.2 mu Drip irrigation, 0.1 acres of irrigated fields with soil contrast. The rapeseed cultivars were “short frame early” (sweetlan type) transplanting on November 20, April 22 harvest, size 8 × 8 inch, single and double strains of white, together 14,600 strains / mu, the rest for the general field cultivation Measures.
