Embodiment 1
[0034] Step 1. Tomato seedling selection: Tomato seedlings are grown with a plug-in substrate, and the substrate is composed of peat, mushroom residue, and vermiculite in a volume ratio of 3:3:2; tomato seedlings are selected from tomato seedlings with four leaves and one heart, and they can bloom after planting and slow seedlings ;
[0035] Step 2, determine the planting density of tomatoes: plant the tomato seedlings in step 1 in the solar greenhouse, plant the tomatoes in the solar greenhouse by wide and narrow rows, with a wide row spacing of 80cm, a narrow row spacing of 60cm, and a plant spacing of 35cm;
[0036] Step 3. Treatment of the solar greenhouse before tomato planting: 1) 30 days before tomato planting, clean the weeds, previous crops and all crops that can parasitize Bemisia tabaci in the solar greenhouse; 2), 7 days before planting, close The tuyere, airtight solar greenhouse, high temperature and stuffy shed for 2 days, eliminate whitefly and egg pupae in the...
