Tomato ethephon ripening should pay attention to what the problem

The use of ethephon ripening tomatoes is a very effective method, there are three ways: 1) post-harvest dipping method. Select the top white fruit, pick it off at the layer and dip for 1 minute (minutes) in 2000--4000mg/kg ethephon solution. After slightly drying, stack 20cm thick layer and place it at 20-25°C. Under ripening, you can turn red one week ahead of schedule. Remove the handle for sale. 2) Whole plant spray. In the late stage of plant growth, 800-1000 mg/kg ethephon can be sprayed throughout the harvest to the upper layer, which not only promotes the redness of the fruit, but also the growth of the leaves. When only the uppermost layer of inflorescence is available, 4000 mg/kg ethephon can be sprayed throughout the whole plant, and the red plants are harvested after red harvesting. 3) Coated fruit on the strain. When the fruit on the top of the fruit when the white, available 2000--4000mg/kg ethephon, hand wearing plastic gloves, plastic gloves and then wear a white line gloves, dipped in ethephon coated fruit, pay attention to the ethetic coated in sepals and fruit The contact is better. The use of ethephon ripening tomatoes must pay attention to: 1 no matter what kind of treatment, must be carried out in the whitening period of the top of the fruit, premature color conversion is slow, even if the color, the color is not good. 2 can not use too much concentration. Concentration is too large, uneven coloring, affecting product quality. 3 The rate of red turning after ethephon treatment is related to ripening period and ripening temperature of fruit. In order to speed up the coloring, in addition to the treatment should be carried out when the top of the fruit white, but also should pay attention to ripening temperature, temperature to 25--28 °C is appropriate, too slow color change, too high (more than 32 °C) fruit with yellow. 4 Ethephon is an acid and should be avoided by direct contact with the hand. Otherwise, it will burn the skin. When you apply the fruit by hand, you should wear plastic gloves to isolate it.
