High returns from using the five-change planting method for overwintering cucumbers
Change dense planting of seedlings to rational sparse planting. In winter, temperatures are low and light is weak, so crop photosynthesis is relatively poor, and only rational sparse planting can achieve high yields. If plants are too dense, they will also grow tall and spindly as they compete for light, and the fruit-setting rate will decline. Poor ventilation also makes them prone to infection by multiple diseases, and dense leaves make spraying difficult. Once the disease spreads, it is very hard to cure completely. Flat beds...
