无遮阴条件下番茄越夏栽培十分困难,夏季气温、土温容易引起植株生长发育不良,特别是入伏以后连续的高温干旱番茄落花,落果严重,各种病虫害随之而来,导致番茄产量低而不稳,品质下降。采取玉米与番茄间作栽培越夏番茄收到增产、增收目的。一、间作效果 1.改善了田间小气候。以高秆作物玉米给番茄遮阴,不仅减少了田间水份的蒸发,提高空气的相对湿度,降低地温和田间温度,而且光照仍能满足番茄生长发育的要求。据观测夏季晴天中午光照在10万勒克斯以上,而带间距地高60厘米处光照为6～7万勒克斯,仍有约6小时的光照充分满足生长发育的需求;10厘米的地温早晨差别不大,而中午和午后比露地降低3～
The cultivation of tomato in summer without shade is very difficult. The temperature and soil temperature in summer can easily lead to poor plant growth and development. In particular, the continuous high temperature and drought of tomato fall into flower and fall seriously after falling into the soil. All kinds of pests and diseases will follow, resulting in low yield of tomato Unsteady, the quality of decline. To take intercropping corn and tomato cultivation summer tomato received stimulation, income purposes. First, the inter-working effect 1. Improved field microclimate. Covering the tomato with high-stalk crop corn not only reduces the evaporation of water in the field, increases the relative humidity of the air, decreases the ground temperature and the field temperature, and the light can still meet the requirements of tomato growth and development. According to the observation of summer sunny noon light at 10 million lux or more, and with a distance of 60 cm high at 60 to 70,000 lux, there are still about 6 hours of light to fully meet the needs of growth and development; 10 cm of ground temperature difference is not big , But noon and afternoon than the open field to reduce 3 ~
