In the process of tomato planting, we need to take corresponding measures for the different growth stages of tomatoes. Below, Kobayashi introduces the summer planting period of the summer and autumn, as well as the management points of the flower and fruit period, hoping to help the vegetable farmers who grow tomatoes.
I. Management of summer and autumn tomato planting period
In order to make the tomato field easy to drain during the rainy season and have better ventilation and light transmission conditions, it is best to use large and small rows and ridges. Drilling the ground first, the method is: start from the side, open a 20 cm wide, 15 cm deep ditch, 50 cm apart (the distance from the center of the ditch to the center of the ditch) to open a second ditch, and then open 80 cm apart Three ditches. That is, the small line spacing is 50 cm, and the large line spacing is 80 cm, which are arranged at intervals. After planting, the soil is ridged.
After ditching, apply 250--500 kilograms of decomposed manure per acre, apply the soil and fertilizer after planting, plant the seedlings at a distance of 30 cm, and cover the soil with water after the soil is covered. Remember to use the saplings 100-150 times before the planting.
Second, summer and autumn tomato flower fruit management
(1) After the initial flowering and fruiting period is managed, the seedling water is poured twice, and the cultivating is carried out. When the plants are deficient in water, watering conditions should be watered. It is mainly based on cultivating and cultivating, and it is necessary to cultivate and protect after watering and raining. In addition, controlling the transmission of locusts and other vectors is an important part of preventing viral diseases. This period can be used 150-300 times of Qingkulix + 600 times spray of Wofengsu 2-6 times, and can also be rooted at the same time; the disease is high in the period of 1000-1500 times of garlic oil or other chemical drugs.
(2) After the first panicle fruit is placed, 25--30 kg of NPK fertilizer per mu, or 300-400 kg of decomposed manure, is applied around the plant. Watering the water between the small rows and rows, and inserting the kidnappers after watering. When the weather is dry, small rows are watered at the same time as the big ones.
(3) The results of the management of summer and autumn tomato results in the positive rainy season, pay attention to spray 300 grams of green ricketts before the rain to prevent disease. Drain water in time after heavy rain. In the rainy season, the effective nutrients in the soil are easily lost. The topdressing method should adopt the method of less application of diligence and cooperate with the foliar application of Wolfen. Summer watering should be carried out in the evening to reduce nighttime breathing consumption. Regularly spray the dry rickle to prevent the disease from happening.
(4) Bind the vines in time after inserting the shelves. Single dry pruning plants are planted early to leave 5--7 spikes, and in the first half of June, 5-6 spikes can be left. Two leaves on the ear are topped. Timely matcha and remove the bottom yellow leaves. The red line of the fruit is harvested, and it should be handled lightly for easy transportation. The immature fruit before the frost should be taken before the cold damage, stored at a temperature of 10-13 ° C and a relative humidity of 90%, and then supplied to the market after red ripening.
Third, autumn delay tomato planting and management
(1) Colonization and management
Planted from the end of August to the beginning of September. The tomato is going to hit the wall and stand in the wind before winter. Therefore, in the layout of the hustle and bustle, you should do something. It is usually a group of 3 畦, 畦 1.2-1.5 meters wide, only planted in the middle. After planting, watering, slowing down the seedlings, grasping the cultivating, and properly controlling the watering.
The first ear of fruit was topdressed and then topdressed. Each standard 畦 was topdressed with 1 kg of NPK fertilizer, followed by watering. Tilt the tomato plants and tie them to the stand or sling.
(2) Timely coverage protection
Most of the fruits can grow up but are still immature before the weather turns cold. This is an important goal for delayed tomato cultivation in autumn. In late September and early October, Yangshuo Wall should be built. When the temperature is low at night, cover the plastic in the evening and touch it during the day. After the frost has fallen, it will be covered in the daytime, and the felt or grass will be covered at night. However, proper ventilation should be performed during the day to reduce the temperature inside the crucible. After covering the film, the humidity inside the sputum is large, and it is easy to cause diseases such as leaf mold, and it can be sprayed with é“果安(Moldproof) 300 times plus von Fengsu 600 times.
