(1) When dividing seedlings, ditch the top of the seedbed with a special mud spoon. The ditch should not be too deep and vertical. Then sprinkle a small amount of water, bury the soil and reset to ensure the cleanliness of tomato seedlings.
(2) Base fertilizer should be applied before planting. Half a month before seedling raising, after leveling the ground, apply appropriate farmyard manure. It should be noted that farmyard manure, as an important base fertilizer, needs to be buried deeply; Then deep furrow is used for high soil moisture, and the appropriate soil moisture width is 1.2m; Then dig a fertilization ditch on the soil moisture. When digging a fertilization ditch, in order not to affect the normal digging of the pond, the fertilization ditch can be tilted appropriately, and then fertilizer (compound fertilizer, potash fertilizer, etc.) can be added. ) can be applied.
(3) Tomato seedling planting: The height of tomato seedling is about 20cm, and the most suitable planting time is 7-8 leaves. But when planting seedlings, we should pay attention to the weather and try to choose sunny days for planting. The spacing between plants and seedlings should be determined according to different tomato varieties. Usually, the spacing between middle-mature and late-mature plants is about 35cm, and the number of plants per hectare is about 52 thousand; The spacing between early-maturing plants and seedlings is relatively small, generally about 25cm, and the number of plants per hectare is about 65 thousand.
After the planting is completed, there are several points to pay attention to: cover the film and water it, and the amount of water should not be too large; Pay attention to keep the temperature (ground temperature above 20℃, air temperature around 33℃); After planting, spray 300 times of Bamlan nutritional protection solution once, and once in the next half month or so; During slow planting, auxin or chlormequat chloride should be sprayed to ensure plant growth.
