Rotation cultivation technique of watermelon-rice-green manure
In order to promote the green and high-quality development of agriculture,improve land use efficiency,and increase farmers'income,the cultivation model of watermelon-rice-green manure was integrated.The key cultiva-tion techniques and benefits of this model were summarized and analyzed.Using the technique of small arch shed culti-vation,watermelons were selected from early and middle maturing and high-quality varieties.Watermelons were planted in early April and harvested in June.When the garden was closed,healthy vines were left in the field as organic fertilizer for rice.High-yield and high-quality mid season rice varieties were selected for rice cultivation,with soft disk seedling cultivation,machine insertion at the end of June,and harvesting at the end of October.15-20 days before harvesting,sprinkle milk vetch seeds as green manure.During the growth period of green manure,pay attention to drainage and flood prevention.In March of the following year,plow and return to the field.This model improves the annual benefits of farm-land while stabilizing rice production,promotes the sustainable development of watermelon and rice industries,and effec-tively reduces the occurrence of field diseases and pests,achieving the effect of weight loss and drug reduction.It is con-ducive to the stable and high-yield of watermelon and rice,and the economic and ecological benefits are improved.
