How do you make the sepals of cherry tomatoes straight?

Cherry tomatoes have high nutritional value and unique flavor, and are the best of both eating and ornamenting, and are favored by the majority of consumers. But how is it grown? What should be paid attention to in breeding? Let's go along.

1. Cultivation method of cherry tomatoes (basic knowledge):

Optimal growth soil: the soil moisture requirement is 60-80{bf}, and the slightly acidic soil with deep soil layer, loose and fertile, and pH of 6-is appropriate.

The best growth temperature: cherry tomatoes like temperature, the suitable temperature for growth and development is 23-28 for Huzuo, and the night temperature is 15-18.

Optimal growth light: the average daily temperature is between 18 21, the daily maximum temperature is between 20 24, the average sunshine is 5 hours a day, and the climatic conditions are very suitable for the growth and ripening of cherry tomatoes.

2. Precautions for cultivating cherry tomatoes:

Fertilizer application: pay attention to the quality of cherry tomatoes, pay attention to the application of organic fertilizer, and control the amount of nitrogen fertilizer. Apply 2500 kg of decomposed manure, or 2000 kg of human and animal manure or 100 kg of vegetable cake, 30 kg of compound fertilizer, and 50 kg of superphosphate per mu as base fertilizer, and adjust the growth through water management.

When harvesting the pre-fruits, every 2-3 canopy fruits are harvested, according to the strength of the growth potential, the water-soluble fertilizer of fertile leaves should be applied 2-3 times, but the appropriate amount of potassium fertilizer should be added.

Watering points: cherry tomatoes belong to the continuous flowering and fruiting of vegetable crops, after entering the flowering period, watering to master the principle of seeing wet and dry (refers to watering once thoroughly, and then wait until the soil is almost dry and then watering the second time, its role is to prevent excessive watering caused by rotten roots and damp pests and diseases), not more watering, not drought, otherwise it will cause flower and fruit drop and physiological cracking.

Pruning essentials: limited growth of varieties, try to promote its growth, have been leaving 2 strong side branches in the upper part, so that it grows upward, pay attention to the balance of the number of leaves and fruits, if the growth is too weak, you can remove part of the flower buds, unlimited growth type is not aimed at early maturity, can be double-rod pruning, because the seed ** is higher. But the production of multiple rows of single-stem pruning.

In order to achieve the purpose of improving quality, enhancing light, promoting aeration and preventing diseases, the old leaves below the harvested fruit ears can be removed.

3. Key points of reproduction:

1. Variety selection: choose the middle and late maturing varieties in the infinite growth type, and plant Taiwan ruby (i.e., the new saint), which has a long production period, high yield, and strong heat and humidity resistance.

2. Plot selection: Cherry tomatoes have strong adaptability to soil, but it is better to have loose and fertile loam or sandy loam soil with convenient drainage and irrigation.

3. Sow seeds in a timely manner and cultivate strong seedlings.

Pest control: 600 800 times of trichlorfon and dichlorvos can be sprayed for Spodoptera liturae and cotton bollworm, and 10{bf} imidacloprid 1000 times liquid spray can be used for aphids. There are four common diseases: cataplexy, early blight, bacterial wilt and viral disease.

In the early stage of the disease, 500 times of 64{bf} alum wettable powder or 400 500 times of 70{bf} zeb wettable powder, or 500 600 times of methyl tobuzin can be sprayed for treatment.

In tomato production, due to the competition between the expansion period of the first ear fruit and the growth of stems and leaves, and the nutrients produced by leaf photosynthesis will generally give priority to the dominant organ, if the fruit is not the dominant organ at this time (in the case of long stems and leaves), then the first ear fruit often does not grow large.

So how to maximize the weight of the first ear fruit without weakening the plant?

First, apply plantar fertilizer, apply 5000 kg of rotting organic fertilizer per mu, and apply three-element compound fertilizer and calcium fertilizer. Flowering and fruiting are sprayed twice with 1000 times borax solution in a row, with an interval of half a month. And pay attention to foliar sprays of 200 times calcium chloride, 100 times superphosphate solution and other supplemental calcium.

As well as nitrogen, phosphorus, potassium, humic acid, trace elements and other foliar fertilizers and plant growth regulators such as brassin, sodium trinitrate.

Second, during the flowering period, attention should be paid to the timely selection of anti-falling pigment and other stained flowers or smeared flower stalks to promote fruit set. In general, the treatment of flowers with such agents not only increases the fruit setting rate, but also facilitates the expansion of the fruit. Generally, 3O 50ppm anti-drop hormone can be used, and mixed with gibberellin, fludioxonil, red pigment, etc., to prevent and control gray mold, prevent repeated treatment, and improve the treatment effect.

Third, when the first ear fruit grows to the size of a walnut (60% of the plants in the field sit on the fruit), it is necessary to water the fruit water in time, and top dressing, 15 kg of urea per mu, 1o kg of potassium sulfate, and then top fertilizer every half a month, and can be applied intermittently with organic fertilizer.

Fourth, pruning and topping in time to reduce nutrient consumption. Generally, 3 or 4 ears of fruit are left in the short season, and 2 leaves are left to tip after seeing buds. In order to inhibit the apical dominance, promote the return of nutrients, and facilitate the expansion of fruits.

Fifth, leave the fruit appropriately. The weight of a single fruit of a variety is not only related to the variety, but also to various factors such as the amount of fruit retained. Generally speaking, the first fruit of the first ear is prone to deformed fruits, if this is the case, it can be thinned and three even fruits (large and medium fruit type) can be selected.

Small fruit type can leave 4 to 5 fruits. Don't be greedy. Even after satisfying the need, the other flowers are not even treated.

Sixth, fruit enlargement is not only about fertilizing and watering, but more importantly, the photosynthesis ability of leaves. Therefore, it is necessary to prevent and control pests and diseases in time to protect the photosynthesis ability of leaves. Do not over-thrash the leaves.

Only after the fruit enters the ripening stage, the lower old leaves can be completely knocked off according to the situation to facilitate ventilation and light.

Generally speaking, the fruit should be placed in a position where it is easy to see light during the low temperature period to facilitate ripening, and in the high temperature period, it should be placed in a hidden place to prevent sunburn and fruit cracking.

Seventh, the concentration of carbon dioxide in the shed is often insufficient, which affects the photosynthesis of crops. Therefore, carbon dioxide gas should be replenished in the morning on a sunny day.

Eighth, the appropriate temperature difference is conducive to the transport of photosynthetic products to the fruit, the general daytime temperature should be about 25 degrees Celsius, the first half of the night 18 degrees, the second half of the night 13 degrees, should not be lower than 1o degrees for a long time.

Low temperature and low sunlight during the day are not conducive to photosynthesis, and low temperature at night is not conducive to the transport of nutrients.

In conclusion, to ensure the expansion of tomato fruits, one cannot count on one or two measures, but on many measures.

Summary. First, reasonable fertilization. In the early stage of tomato growth, we should pay attention to raising roots and strengthening trees, and at the same time supplement various nutrients and trace elements, especially boron and calcium and other elements.

Second, the rational use of drugs, especially the use of pesticides, should be prepared in strict accordance with the use of concentration, to avoid the concentration of pesticides is too high, the occurrence of pesticide damage, affecting the growth of tomato calyx, and eventually resulting in tomato calyx yellow and short.

The third is the management under adversity conditions, the purpose of cultivating strong trees in the early stage is to improve the resistance of plants under adversity conditions, especially in the case of low temperature and continuous rainy days, timely measures should be taken to strengthen the absorption of light by plants, so as to promote the synthesis of chlorophyll in tomato leaves and avoid affecting the growth of tomato calyx.

Fourth, reasonable use of pesticides to promote the growth of tomato calyx, at present, many farmers on the market will add a small amount of gibberellin to promote the growth of calyx when preparing some anthers, this method can be taken, but gibberellin concentration control is not easy to cause problems, so it is recommended that farmers can use more mature products on the market, such as the "real long calyx" produced by Dr. Lenong.

How to make tomato sepals hypertrophied.

Hello, I have seen your question and am sorting out the answer, please wait a while

First, reasonable fertilization. In the early stage of the growth process of Xihong persimmon, we should pay attention to raising the roots and strengthening the trees, and at the same time supplement various nutrients and trace elements, especially boron and calcium and other elements. Second, the rational use of drugs, especially the use of pesticides, should be prepared in strict accordance with the use of concentration, to avoid the concentration of pesticides is too high, the occurrence of pesticide damage, affecting the growth of tomato calyx, and eventually resulting in tomato calyx yellow and short.

The third is the management under adversity conditions, the purpose of cultivating strong trees in the early stage is to improve the resistance of plants under adversity conditions, especially in the case of low temperature and continuous rainy days, timely measures should be taken to strengthen the absorption of light by plants, so as to promote the synthesis of chlorophyll in tomato leaves and avoid affecting the growth of tomato calyx. Fourth, take a reasonable agent to promote the growth of tomato calyx, at present, many farmers on the market will add a small amount of gibberellin to promote the growth of calyx when preparing some anthers, this method can be taken by rock, but the concentration of gibberellin is not well controlled, it is easy to produce the problem of jujube, so it is recommended that farmers can use more mature products on the market, such as the "real long calyx" produced by Dr. Lenong.

The quicker way is to add 1-2 drops of gibberellin Qifeng to the anthers of Songdian, which can significantly make the sepals grow and turn green, or add gibberellic acid to the anthers.
