Cold tomato coloring poor drug reminder red taboo

After entering several cold winter months, the tomato could not turn red due to the temperature not meeting the requirement of lycopene formation, and reding of the pharmaceutical before picking is an effective measure to promote the early listing of tomatoes. However, in the actual red process, the growth of the plants is often inhibited due to improper handling, and some of them are prone to phytotoxicity.

The following problems should be noticed when the drug is red: (1) Red should not be premature. Generally, when the fruit is fully grown up, the effect of redness is best. If the fruit is still in the mature period and is not fully grown up, it is eager to urge the red to appear uneven phenomenon of uneven coloration.

(2) The concentration of the drug should not be too high. Tomato redness is mostly used 40% ethephon, 4 kg per 50 ml ethephon plus water, mixed and used. If the concentration of the liquid is too high, the leaves of the plant's base will be damaged, causing the leaves to yellow and produce obvious symptoms of drug damage.

(3) The number of red fruit per plant should not be too much. The red fruit per plant is generally 1 to 2 at a time. Because a single plant reminds red fruit too much, it is easy to produce phytotoxicity if the amount of the plant is too large.

(4) The liquid should not be contaminated with leaves. If the liquid is contaminated by the leaves, it will cause the leaves to yellow. The specific practice of redness is: use a small piece of sponge to dip the liquid and smear the surface of the fruit; you can also wear cotton gloves to dip the liquid and spread the surface of the fruit.
