Tomato planting wants high yield and high volume, these five management points need to be valued!

Tomatoes can be planted all year round. In the process of planting, the farmers need to be carefully managed, especially to adjust the plants in time. Sometimes the growth of tomatoes is affected by some factors, and farmers should deal with them in time. We often have measures such as pruning, forking, topping, keeping flowers and fruits, and thinning flowers and fruit. So today, Xiaobian talks about how these aspects are managed. Let's take a look.

Pruning

For infinitely growing tomato varieties, it is suitable to use single dry pruning and head turning.

(1) Single dry pruning. Leave only one trunk, remove all side branches, and leave fruit on the trunk. According to different cultivation methods and methods, 4-10 ear fruits are generally selected, but the wintering flowers retain the ear fruits appropriately.

(2) Change the head and pruning. The trunk leaves 2 true leaves in front of the 3rd flower spikes. After the fruit is placed, a side branch is placed in the middle instead of the main stem. After the 3 spikes are left on the side branches, the tops are topped, and the head is changed 2-3 times in this way.

2, snoring

Tomato side buds have strong germination power, and often multiple lateral branches grow at the same time. In order to promote root growth and hair growth, the initial snoring time can be postponed until the scorpion is about 5 cm long, and can be wiped off in time when the 杈 is 1-3 cm long. Snoring is generally combined with tying vines. It should be snoring in the morning on a sunny day. At this time, the wounds heal quickly and the disease infection is alleviated. Be careful to first hit the healthy plant and then hit the diseased plant.

3, topping

When the ear on the main branch grows to a certain number, two true leaves are topped above the ear, which is called topping. After the topping, the growth point stops growing, and the nutrients produced by the leaves can be concentrated to supply fruit growth, which promotes the fruit to grow and mature. When picking the heart of the tomato plant, do not smash all the tops. You should leave 2-3 leaves, and use them to produce nutrients for photosynthesis, so that the lower flowers and fruits can grow, and it can also play a certain shade to avoid the appearance of the upper fruit. Illness. Note that the topping should also be carried out on a sunny day. In addition, the limited growth type tomato has the characteristics of self-sealing, so no artificial topping is required.

4, flower protection fruit

Overwintering tomatoes, due to environmental factors such as low temperature, high humidity, insufficient light, etc., are prone to poor flowering, poor pollination and fertilization effects, resulting in low fruit setting rate and even falling flowers. In order to increase tomato yield, especially early yield, farmers are advised to use tomato spirit or 2,4-D to treat flowering tomatoes in time. (1) If using tomato spirit: When the first inflorescence of tomato has 2-3 flowers open, 20-30 mg / liter of tomato spirit spray can be used to promote fruit enlargement. (2) If using 2,4-D: When the tomato is flowering, use the brush to rub 15-20 mg / liter of 2,4-D liquid to spread the pedicel, be careful not to get the liquid on the stem, so as not to cause phytotoxicity. .

5, thinning flowers and thin fruit

Before treating the inflorescence with tomato spirit or 2,4-D, if the number of flowers per panicle is found to be excessive, it is necessary to remove the deformed flower and the extra small flower first, and generally 4-5 flowers per ear are retained. At the same time, if there are too many fruit, you should also timely fruit thinning. Generally, early-ripening tomatoes retain 4-5 fruits per ear, while late-ripening tomatoes retain 3-4 fruits per ear, which helps to promote tomato fullness.

The above is the scientific management point of tomato. The above five points play a very important role in the growth process of tomato. Farmers who grow tomatoes must master it well, and rationally pruning, crossing, picking, removing old leaves and protecting flowers. Protecting fruit, thinning flowers and thinning fruit, achieving the goal of high yield and high yield of tomato.
