In recent years, many vegetable farmers have preferred to grow tomatoes in large sheds, which are more efficient in producing tomatoes, and today give you details of how and how they are managed。
I. Choice of varieties of tomatoes grown in sheds
The selection results are highly capable and resistant to the disease, the “santas” and the “cherry red”. The fruit varieties of the “santa” are date-shaped and the “cherries red” varieties are generally rounded。
Ii. Scrolling of tomatoes in sheds
1. The suitable planting period in the pre-scaling seed treatment area is 12-16 june. The tomato seed is immersed for five minutes with a temperature of 55°c, then immersed in 30°c water for three to four hours, immersed in 10% of the sodium phosphate solution for 20 minutes, then washed three to four times with clean water, removed the slime from the seed and mixed in the same amount of sand。
2. The seeding is broadcast live in large sheds and is followed by the application of 5,000 kg of corroded organic fertilizer, 20 kg of potassium nitrogen and 20 kg of calcium perphosphate after harvesting. It is then made 150 cm wide, opening a ditch 2 cm-3 cm deep, and three ditches each. Each set of four to five seeds, 20 centimetres away, spreads the dust behind it and then waters it. Open the front and back. Winds are closed in the event of a rain storm, in order to prevent the storm from washing and exposure, which usually takes place four days in three days。
Iii. Management of seedlings growing tomatoes in sheds
1. Water can be used in the morning or evening to keep the soil dry and wet if the soil is dry。
2. A seedling moisturizes its seedlings at the time and time of the birth of two leaves, two seedlings each, 20 centimetres apart and weeding in time。
Iv. Management of the bouquets for the cultivation of tomatoes
1. The whole branch is established at the beginning of the flowering season, with one seedling each and 4,000-4,500 acres. Cherry tomatoes are grown in large quantities and have a low level of verticality and should be mounted as long as 50 centimetres are grown in order to prevent fallback. Cherry tomato side branches are very strong and usually have a dry whole branch at production level, with two strong branches selected and the other side branches wiped out in time, usually without hitting the top. The yellow leaves should be removed in time to reduce nutrient consumption and to light up the air。
2. 25 ppm anti-defeating or 15 ppm2. 4-d pollen. Cherry tomatoes produce more flowers per ear, with 20 - 30 fruits chosen for good sitting fruit, to sterilise other figs, malformations and rotten fruit。
3. Fertilizing during flowering seasons and fertilization, 150 kg/acre of corroded cannabis seed cakes. After the first sibling, 10 kg of ammonium, 25 kg of potassium sulphate and 20 kg of urea were followed by the acre; after the second sibling, 20 kg of potassium sulphate and 10 kg of urea were followed by the acre。
V. Responsibility of responsible responsibility for the responsibility
When fully mature, harvests should be carried out in a timely manner, with the retention of a chip and a piece of fruit。
Vi. Pest and pest management in the trunks of tomatoes
1. Aphids are protected against aphids with oxidated ointment on the basis of silver grey membrane in the vents of the shed。
2. 65 per cent of the end-of-life disease is treated with 500 times the dysentery。
3. Plasmodium disease is 50 per cent treated with 1,500 times the wettable powder。
When moths are found in the shed, they are treated in a timely manner with the rapid use of tungsten and thionphos-methyl, with a focus on the tipping point and the ear of the fruit, so that they are sprayed。
5. The virus is disinfected with 1 per cent l of cologne or 1 per cent with sodium phosphate。
