In production, it is commonly used to preserve fruits and fruits. Commonly used scallop hormones are 2,4-D, tomato spirits, and anti-dropping agents. When used by growers, they often focus on concentration and high-dose medications, ignoring the details of use and temperature requirements. Due to the excessive management of tomatoes, the growth potential is not neat and the flowering ears spend a single time, so that the buds with different growth rates of one ear are used. Although the same concentration but different flowering periods, different shapes of fruit, such as papillae, will be produced. Because the role of hormone drugs in different temperature conditions is different, the sensitivity to fruit stimuli is also not the same. The vegetable farmers often ignore the temperature during the flowering process, and the habit of using more drugs to “get big†makes the original due to temperature. The concentration of high-concentration agents that are already high in concentration is higher and higher, and the phenomenon of fruit malformation and fruit cracking often occurs.
During the flowering period, some farmers also ignored the openness of flower buds and prematurely sprayed flowering hormones or growth stimulating agents on young flowering plants that have not yet developed buds, causing immature flower buds to grow too fast after stimulation, and the growth of peels and fruit tires. Out of sync, the fruit phenomenon that caused the empty cavity of fruit is widespread.
Control methods:
1. Strengthen water and fertilizer management. Standardize fertilization and watering, increase the proportion of organic fertilizer and potash fertilizer, strive to maintain a consistent growth potential, and neat flowering is the basis for good drug use.
2. Bumblebee pollination. The use of bumblebee pollination can eliminate the cost of medication and artificial labor.
3. Vibration pollination. Artificial field vibrations are used to pollinate already open flowers.
4. Strict implementation of silk flower technology. In the same inflorescence, when 3-4 buds show flower buds and yellow corollas, spray flowers and mark them. Do not repeat medications (preferably add red or other pigments). Now, there are ready-made and well-prepared pharmaceuticals that both protect the flowers and protect the flowers against Botrytis cinerea infection and once in place.
5. Grasp the timing of spraying. The buds with inconsistent flowering stages were treated separately, and the unopened buds were covered by hand. Only open flowers were sprayed and the stems could not be painted. The flowering buds that had not yet exposed the yellow corolla were prevented from generating malformation due to inconsistent flowering stages.
6. Select “Following anthers†for optimum flowering and fruit preservation that does not require strict temperature control. You can choose to use fruit mold Ning (Bao Guo Ning No. 2), high yield agent No. 2, gold preserved fruit and tomato Ling (2 kg liquid) plus Shi Lok (10 ml) can be.
