Second, third and fourth ear empty ear. Causes: 1. Too much fruit in the lower ear. 2. Insufficient nutrients, poor flower bud differentiation, and therefore more empty ear phenomenon.

Third, the upper ear hollow fruit more. Reasons: 1. When the upper fruit of the tomato enters the fruit-expanding stage, it is in the low-temperature, widow-lit season after entering the winter. To promote the transformation of the lower fruit, many vegetable farmers pick up the leaves excessively. 2. Watering and fertilizer reduction in the later period. Many vegetable farmers stop watering and fertilizing tomatoes and three panicles when they are immature.

Response measures: 1. Remove the first flower of each spike, spend more, early fruit thinning, and leave good fruit. Each flower can spend 6 to 8 flowers, when the tomato grows to the size of the pigeon egg, remove the deformed, injured and too large and small fruit, leaving 3 to 5 fruit per ear. 2. Control points spend time and dosage. If you spend time improperly, it is easy to form a stalemate too early, and it is easy to form a crack if it is too late, which will affect the commodity. The flower on each ear starts from the second flower, and each time it is basically 2 to 3 flowers open on the same day. At this time, it starts to spend, and the time is best when the flowers are just open in the morning. For point anther concentrations, the preparation concentration should be slightly higher at low temperatures and slightly lower at high temperatures. 3. The fruit and fertilizer season should keep up. 4. The leaves should not be excessive in the late period. During the period of fruit color conversion, the vegetable grower not only removed the lower leaves of the ear, but also removed many leaves from the upper part of the fruit in order to promote fruit color conversion and increase light. The leaves were too few, which affected the photosynthetic accumulation of leaves and nutrient deficiency, resulting in hollowing. Therefore, snoring and picking leaves in the middle and late stages of growth are appropriate and should not be excessive.
