Greenhouse tomatoes using continuous picking and pruning can significantly increase the quality of fruit harvested. Its main supporting technology is:
Suitable cultivars
Selected resistance, high yield, high fruit set rate and good quality hybrids.
Suitable mouthwash
Early spring, late autumn and wintering are all available. Sowing should be selected to suit the sowing period in the region.
Soil fertigation
After the earthworms are leveled, apply 8000 kg of farmyard manure, 50 kg of diammonium phosphate, 35 kg of potassium sulfate, 10 kg of urea (spray 40 cm deep after spreading the ground), and make 1.2 m wide and 20 cm high. Concave-shaped stilts, watered in the center, with a groove width of 20 cm, covered with sufficient water after the ditch.
Proper colonization
In autumn and winter, it is necessary to ensure that the shed film is not damaged and has the effect of preventing rain and cooling. Each row was planted in a single row with a spacing of 35 cm and 1800 per mu.
Pruning method
Firstly, when all the first inflorescences of the main branch stems are to bloom, and the second inflorescence is about to flower, leave two leaves at the top of the second inflorescence to serve as the first basic branch; at the same time, leave the first basic branch to the lower one of the first inflorescence. Lateral branches, and the other side branches destroyed; until the first inflorescence of this side branch most of the flowering, the second inflorescence is about to flower, then leave two leaves in the upper part of the second inflorescence to serve as the second basic branch; then the second basic branch One side branch under the first inflorescence is left as the third basic branch; in turn, the heart is picked five times, five fruit branches are circled, and each fruit has ten fruit branches; the second inflorescence has been flowered and treated with the anti-droplet, and is held by the right hand. The base of the first inflorescence is twisted outward by 85 to 90 degrees and then gently pressed down so that it is approximately perpendicular to the previous basic branch, ie the twisted branch is reached.

Coating auxilliaries, also known as paint accessories, the department of the preparation of coating auxiliary materials, can improve coating performance, promote the formation of coating film. There are many kinds, including drying agent, toughening agent, emulsifier, thickening agent, pigment dispersing agent, defoaming agent, levelling agent, anti-skidding agent, matting agent, light stabilizer, mildew proofing agent, antistatic agent (see plastic assistant), etc., among which the largest amount is drying agent and toughening agent. At present, the research of coating auxilaries, to be used for water emulsion paint auxilaries as the focus.
