Embodiment 1

[0010] Example 1. Tomatoes were cultivated in a solar greenhouse with delayed stubble in autumn. The planting variety was Fenjiamei. It was sown on July 5 and planted on August 10. The place was in a vegetable greenhouse in Shouguang, Shandong.

[0011] The size of the tomato fruit is basically finalized. When the fruit is in the period of color change, implement the method of preventing the tomato fruit from cracking. When it is sunny, use your left hand to pinch the branch position of the fixed fruiting branch and the main cob, and place the branch at a distance of 2-3 cm from the branch position. The main cob rotates 180°-270° clockwise.

[0012] Half of the tomatoes in the solar greenhouse of 800 square meters implement the method of preventing tomato fruit from cracking, and the other half of the tomatoes are managed as a control according to conventional methods.

[0013] After testing, the tomato fruit cracking rate of the main cob torsion was 4.2%, and the yield per mu...

Embodiment 2

[0014] Example 2: Tomatoes were cultivated in early spring in a solar greenhouse. The planting variety was Provence, sown on December 10, and planted on February 5 of the next year. The place was in a vegetable greenhouse in Shouguang, Shandong.

[0015] The size of the tomato fruit is basically finalized. When the fruit is in the period of color change, implement the method of preventing the tomato fruit from cracking. When it is sunny, use your left hand to pinch the branch position of the fixed fruiting branch and the main cob, and place the branch at a distance of 2-3 cm from the branch position. The main cob rotates 180°-270° clockwise.

[0016] Half of the tomatoes in the solar greenhouse of 500 square meters implement the method of preventing tomato fruit from cracking, and the other half of the tomatoes are managed as a control according to conventional methods.

[0017] After testing, the tomato fruit cracking rate of the main cob twisted was 4.1%, and the yield per m...

Embodiment 3

[0018] Example 3: Tomatoes were cultivated overwintering in a solar greenhouse. The planting variety was FA-189, sown on September 10, and planted on October 20. The place was in a vegetable greenhouse in Shouguang, Shandong.

[0019] The size of the tomato fruit is basically finalized. When the fruit is in the period of color change, implement the method of preventing the tomato fruit from cracking. When it is sunny, use your left hand to pinch the branch position of the fixed fruiting branch and the main cob, and place the branch at a distance of 2-3 cm from the branch position. The main cob rotates 180°-270° clockwise.

[0020] Half of the tomatoes in the solar greenhouse of 500 square meters implement the method of preventing tomato fruit from cracking, and the other half of the tomatoes are managed as a control according to conventional methods.

[0021] After testing, the tomato fruit cracking rate of the main cob torsion was 2.5%, and the yield per mu was 12051.6 kg. Th...

Abstract

The invention discloses a method for preventing tomato fruits from cracking. When the tomato fruits are in a veraison stage with a basically fixed size, the branching positions between the fruiting branches and main spike stalks are fixed, and the parts 2-3cm away from the branching positions on the main spike stalks are rotated 180-270 degrees clockwise or anticlockwise. In sunny days, the method can be adopted to twist the main spike stalks of the tomatoes to partially damage the phloem so as to reduce transportation of photosynthates, lower growth speed of flesh, and enable the growth speeds of peel and flesh to be consistent, thereby playing a role in fruit cracking prevention. Tests show that the fruit cracking rate can be reduced by more than 15%.

Description

technical field [0001] The invention relates to a method for preventing tomato fruit from cracking, and belongs to the technical field of agriculture. Background technique [0002] Tomato cracking means that when the tomato fruit is about to ripen, the pericarp cracks, and the embryonic tissue and seeds are turned out along with the pericarp, causing the navel of the fruit to crack, and some stripes appear on the surface of the fruit near the stem or on the top or side of the fruit. Specifically, it is divided into top crack, crack and zipper fruit. Tomato cracking is very common in solar greenhouses and is a physiological disease. After its occurrence, it not only directly affects the appearance and price of the product, but also the crack part may be infected with early blight, late blight or infected by bacteria and rot, losing commodity value. [0003] Tomato fruit cracking is mainly due to the asynchrony between the growth of the pulp and the growth of the peel, the r...
