Description

Technical Field

[0001] This invention relates to the field of cherry tomato cultivation technology, specifically a method for pruning cherry tomatoes suitable for organic substrate cultivation. Background Technology

[0002] Cherry tomatoes are rich in protein, soluble sugars, organic acids, minerals, and abundant vitamins and amino acids. The fruit is soft, juicy, and has a sweet and sour taste. Lycopene contains cinnamic acid and chlorogenic acid, which can antagonize substances in food that can produce carcinogens. Cherry tomato plants grow rapidly, branch vigorously, and are prone to flower and fruit drop, resulting in a significant conflict between vegetative and reproductive growth. Therefore, in substrate cultivation, it is essential to prune and shape the cherry tomato plants to improve the plant environment, coordinate the sink-source relationship, and regulate nutrient transport to achieve high yield and quality. Thus, adopting reasonable pruning and cultivation management methods in greenhouse cultivation of cherry tomatoes can effectively save cultivation costs, simplify tomato cultivation management procedures, and improve water and fertilizer utilization, thereby increasing the yield and quality of cherry tomatoes. Traditional tomato pruning methods include single-stem pruning, double-stem pruning, and continuous topping and replacement pruning, among others.

[0003] Traditional pruning methods, due to their high water and fertilizer requirements, tendency to premature aging, short fruiting period, and cumbersome management, cannot fully realize the yield potential of indeterminate cherry tomato varieties, especially for hydroponics. Single-stem pruning is suitable for dense planting, has good early maturity, and is technically simple, but requires a large number of seedlings, resulting in high costs and premature aging, leading to low overall yield. Double-stem pruning saves on seed and seedling costs, resulting in a longer growing season, vigorous growth, longer fruiting period, and higher yield, but early yield is low and early maturity is poor. Continuous topping and replacement pruning can improve quality, extend the fruiting period, and increase yield, but the operation is relatively cumbersome and requires sufficient fertilizer and water to prevent premature aging. Therefore, a new pruning method is needed to meet the needs of hydroponics for cherry tomato cultivation. Summary of the Invention

[0004] The purpose of this invention is to provide a pruning method for cherry tomatoes suitable for organic substrate cultivation. This technology combines horizontal planting and double-stem pruning to overcome the shortcomings of double-stem pruning. Double-stem pruning saves on seed and seedling costs, resulting in a longer growing season, vigorous growth, longer fruiting period, and higher yield, but it also has low early yield and poor precocity. Horizontal planting, on the other hand, promotes rapid early growth, early fruiting, and high yield. Furthermore, horizontal planting avoids excessive seedling growth that could reduce yield, and it also dwarfs the plants, reducing lodging, improving ventilation, and effectively lowering disease incidence.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for pruning cherry tomatoes suitable for organic substrate cultivation, comprising the following steps:

[0006] S1. Horizontal planting: After transplanting cherry tomatoes, when the plants grow to about 40cm, bury the base of the stem below the first pair of heart leaves in the soil.

[0007] S2. Selecting a vine: Select a strong lateral branch on the main vine to be cultivated as the second main vine;

[0008] S3, Trellising: Trellise the main vine and the second main vine separately, one rope per plant, and manually wrap them every 5 to 7 days to keep the main stem growing upwards;

[0009] S4, One-time fruit retention: Leave 7 fruit clusters on the main vine and the second main vine respectively in step S3;

[0010] S5, Leave 3 leaves after the 7th spike of fruit that grows in step S4;

[0011] S6. First topping: After the third leaf grows out in step S5, pinch off the tips of the main vine and the second main vine respectively.

[0012] S7. Retain lateral branches: Five lateral branches are retained on the main vine and the second main vine respectively in step S2;

[0013] S8. Secondary fruit retention: Leave one cluster of fruit on each of the five lateral branches that grew out in step S7;

[0014] S9, Secondary Leaf Retention: After the spikelet of fruit grows in step S8, retain 3 leaves;

[0015] S10, Secondary topping: After the third leaf grows out in step S9, pinch off the tips of the lateral branches.

[0016] Preferably, in step S1, the base of the stem is buried about 5cm deep in the soil, and care should be taken to keep the soil moist during burying.

[0017] Preferably, in steps S2 to S10, leaves and branches not discussed in the above steps are removed when they reach a length of about 5 cm.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] In this invention, cherry tomatoes are planted horizontally and trained using a double-stem system, which compensates for the shortcomings of the double-stem system. The double-stem system can save on seed and seedling costs, resulting in a longer growing season, vigorous growth, longer fruiting period, and higher yield, but it has low early yield and poor precocity. In contrast, tomatoes planted horizontally grow faster in the early stages, bear fruit earlier, and have higher yields. At the same time, planting tomatoes horizontally can avoid the yield reduction caused by excessive seedling growth, and it also has the effect of dwarfing the plants, thereby reducing lodging, improving ventilation, and effectively reducing the incidence of disease. Detailed Implementation

[0020] The specific embodiments of the present invention are described in detail below:

[0021] A pruning method for organically grown cherry tomatoes.

[0022] Includes the following steps:

[0023] S1. Horizontal planting: After transplanting cherry tomatoes, when the plants grow to about 40cm, bury the base of the stem below the first pair of heart leaves in the soil about 5cm deep. Do not bury it too deep. At the same time, pay attention to keeping the soil moist when burying it so that the base of the stem buried in the soil can quickly grow adventitious roots.

[0024] S2. Selecting a vine: Select a strong lateral branch on the main vine to be cultivated as the second main vine;

[0025] S3, Trellising: Trellise the main vine and the second main vine separately, one rope per plant, and manually wrap the vine around the rope every 5 to 7 days to keep the main stem growing upwards;

[0026] S4, One-time fruit retention: Leave 7 fruit clusters on the main vine and the second main vine respectively in step S3;

[0027] S5, Leave 3 leaves after the 7th spike of fruit that grows in step S4;

[0028] S6. First topping: After the third leaf grows out in step S5, pinch off the top of the main stem and the second main stem respectively to prevent the main stem from growing upward;

[0029] S7. Retain lateral branches: Five lateral branches are retained on the main vine and the second main vine respectively in step S2;

[0030] S8. Secondary fruit retention: Leave one fruit spike on each of the five lateral branches that grew out in step S7, and leave a total of 24 fruit spikes on the main vine, the second main vine, and the lateral branches.

[0031] S9, Secondary Leaf Retention: After the spikelet of fruit grows in step S8, retain 3 leaves;

[0032] S10, Secondary topping: After the third leaf grows out in step S9, pinch off the tips of the lateral branches.

[0033] Preferably, in steps S2 to S10, leaves and branches not discussed in the above steps should be removed every 5 cm or so.

[0034] Preferably, cherry tomatoes are planted horizontally and trained using a double-stem system. This approach compensates for the shortcomings of the double-stem system, which saves on seed and seedling costs, resulting in a longer growing season, vigorous growth, longer fruiting period, and higher yield. However, it also results in lower early yields and poor precocity. In contrast, horizontally planted tomatoes grow faster in the early stages, bear fruit earlier, and have higher yields. Furthermore, horizontal planting avoids excessive vegetative growth that could reduce yields, and it also dwarfs the plants, thus reducing lodging, improving ventilation, and effectively lowering the incidence of disease.
