Production performance: In 2006, the provincial early-maturing group conducted a regional experiment with an average yield of 3112.7 kg per mu, an increase of 21.2% over the control Jingxin No. 1. In 2007, the trial yielded an average yield of 3063.2 kg per mu, an increase of 23.3% over the control Jingxin No.1. In 2008, the provincial early-maturing group produced a test with an average yield of 2890.4kg, an increase of 11.97% over the control Jingxin 1.
Appropriate areas: Early cultivation and planting throughout the province.
Cultivation Techniques:
1, sowing date: cultivation in the middle of February cultivation, mulching film cultivation in early March nursery, seedling age of about 30 days. When planting heavily, grafting should be used to prevent the occurrence of wilt disease.
2, density: 600 strains / mu or so, double or triple vine pruning. The roots were removed in time for fruit setting, and the second or third female flower was selected to leave one fruit per plant.
3, field management: Apply enough base fertilizer, pouring foot bottom water, stop irrigation 7 days before harvest, control locusts, anthrax, blight and other diseases and pests.
