Prevention of defeat in summer tomatoes
As the tomatoes grow hotter over the summer, they are more difficult to manage. If the management measures cannot keep up, it is very easy for the tomatoes to lose. Therefore, during this period, tomato should take measures to promote the healthy growth of the plant. The main points should be as follows:
First, timely pruning, reduce nutrient consumption Summer temperatures are high, prone to prosperous growth, resulting in imbalance between vegetative growth and reproductive growth, it is easy to cause plants to bear fruit after three or four capsules began to lose. In order to control the growth of plants and reduce nutrient consumption, the most direct way is to timely pruning. The timely removal of old leaves, dead leaves and diseased leaves from the lower part of the plant not only reduces nutrient consumption, but also effectively controls the spread and spread of the disease. It is conducive to ventilation and light transmission and promotes vigorous growth of plants.
Second, a reasonable watering and fertilization, to avoid root watering and timely irrigation and fertilizer, can provide adequate nutrients for the growth and development of plants, which is to prevent plant aging is the key measure. However, top-dressing should pay attention to scientific and reasonable, so as to avoid premature aging due to improper fertilizer and water. The best time for topdressing is after the harvest of each pod, in summer, the chicken manure can be used to flush with the water, add appropriate amount of potash fertilizer, generally can add 10 kg per acre each time, can also flush high potassium fertilizer It is advisable to use 15-20 kilograms per acre for each application. Watering should be done before 10 o'clock in the morning or after 4 o'clock in the afternoon. Avoid watering at noon. Also pay attention to the amount of water should not be too large, avoid flood irrigation, so as not to cause root injury, leading to premature plant failure.
Spraying growth regulators to promote plant growth. When the plant growth is weak, foliar sprays can be sprayed on leaves; cytokinins can be sprayed when the leaves turn yellow; 6000-8000 times can be sprayed to prevent premature aging of the roots. Love more.
Fourth, disease prevention and pest control, to ensure that plants grow robustly, disease prevention and pest control is also an important measure to prevent tomato failure, summer tomato disease often occurs with tomato early blight, late blight, leaf mold, etc., should pay attention to early prevention rule. Early disease, early blight can be controlled by 75% of 600 times of Bacteria; late blight and diseases can be controlled by 72.2% of Prec 600 times; Leaf Blight and bacterial leaf spot can be used 47% of Garrinone Insect pests are mainly to prevent aphids, leafhoppers, thrips, and whiteflies. The insect nets should be set mainly at the tuyere's tuyere. For pests that infiltrate into the shacks, 3% acetamiprid can be used to mix 1500 times with 25% of the pests. The buprofezin (Pentazolone) was used for prevention and treatment. When there was leaf pupa, 1.8% of avermectin 2000 times was added to control.
Fifth, timely harvesting, prompting the plant early fruiting tomatoes promote early harvest of fruit. This will not only reduce nutrient consumption, but also prevent premature senescence of plants, and will also promote plant-wide results.
It is composed of a cotton Swab, a plug cap and a sleeve. One end of the sleeve is closed, the plug cap covers the open end of the sleeve, and the cotton swab is located in the sleeve. The plug cap is composed of an inner plug and an outer cap. The inner plug is located in the outer cap. There is a circular gap between the lower end of the inner plug and the outer cap. The edge of the sleeve is located in the gap of the plug cap. The cotton swab is a rod cotton swab. The lower end is wrapped with nylon fibers, and the upper end is connected with the lower part of the inner plug. The sterile cotton swab is convenient for clinical use, and does not require hands to touch the cotton swab, which improves the aseptic operation conditions.
