Talk about the management skills of loofah and control the length of loofah

If we want loofah to have a certain high yield, we must have a certain level of high-level management. Here I will tell you how to better manage loofah.

1. Control the length of the melon strips.

The length of the loofah strips is an important factor in determining whether the loofah is popular with vegetable buyers. Because the types of packaging boxes ordered by vegetable buyers are limited, they prefer loofahs that meet the length of the packaging boxes. Taking Shouguang as an example, in general, 40-50 cm long loofahs meet their requirements. To control the length of the loofah strips, you should do the following:

1. Choosing the variety is the most important thing: Before choosing a variety, you should investigate the market and choose a variety that suits the tastes of local vegetable vendors and consumers.

2. The concentration of anthers has an effect: The concentration of anthers usually used is: 10-15 ml of fruit-setting agent, 8 ml of 2,4-D, 15 ml of Aiduoshou, plus an appropriate amount of anti-drop agent and Luffa Shunzhiwang, for 4 catties of water. Such a concentration can ensure that the growth of melon strips remains at a normal level. Among them, fruit-setting agent and 2,4-D can affect the length of melon strips. When the dosage of these two agents is lower than the normal dosage, the melon strips will grow longer, otherwise they will grow shorter.

3. When the indoor temperature of the greenhouse is between 27-30℃, the melon strips grow normally.

4. Observe the growth of the plants: If the plants are growing too vigorously, you can leave a few more melons to balance the nutrition and prevent individual loofahs from becoming "overweight" due to excessive nutrition. Otherwise, you can leave fewer melons to ensure adequate nutrition.

5. Pick at the right time.

2. Adjust the straightness and bend of the melon strips.

Many books and newspapers say that if the loofah is too bent in the young stage, it can be solved by hanging stones or using hormones. In fact, this is not necessary, because the loofah has a strong ability to sit. When the loofah is bent, it can be picked immediately. The next one will sit and grow quickly, and it will not have a significant impact on the overall yield.

3. Adjust the color of the melon strips.

The color of the loofah skin depends on the variety, but some external conditions will also have some influence on it. To make the loofah bright in color, you should do the following:

⑴ Prevent damage by whiteflies. Whiteflies mainly suck the juice of leaves, which damages the melon flesh, reduces the function of leaves, and then affects the color of melon strips. ⑵ Spraying multi-element micro-fertilizer on the leaves can effectively improve the color of melon strips. ⑶ Avoid shading caused by too many leaves, which makes the color of melon strips dull.

4. The relationship between melon strips and flowers.

Nowadays, the loofahs on the market all have flowers on their heads. So, how can we make the blooming time coincide with the harvesting period of the loofah strips? There is also a science to this:

⑴ If the dosage of 2,4-D in the anther is too high, the flower will not open after the melon strips grow into shape, and the melon strips will grow slowly. ⑵ If the melon stem is too small, the flower will not open, and the melon strips will grow slowly.

Therefore, we must be careful and meticulous when managing the flowers of loofah to ensure that the melon strips can grow fast and the flowers can bloom at the same time when they are picked. At the same time, we must prevent the flowers of loofah from rotting. Liu Chunxiang, a vegetable expert from Shouguang Vegetable Association, summarized the causes and prevention measures of loofah flower rot as follows:

1. Dry and rotten flowers. ⑴ Symptoms: The edges of the petals are dry and rotten, and the entire petal is not fresh. ⑵ Disease analysis: This may be a symptom of vine blight on flowers. It is more serious in weak light conditions, especially after a series of cloudy days. ⑶ Solution: Spray methyl thiophanate or Dasheng or Shibaogong to reduce the occurrence of the disease.

2. Water rot. ⑴Symptoms: Water rot starts from the edge of the petals. In severe cases, the petals have symptoms of dripping water. Sometimes there is a bad smell, sometimes not, but there is white mold. ⑵Analysis of the disease: The case of a bad smell but no hair may be bacterial soft rot, and the case of white mold may be flower rot or cotton blight. Both of these cases occur under high temperature and high humidity. ⑶Solution: For bacterial soft rot, you can spray streptomycin and phytotoxin on the leaves, or you can spray copper preparations such as chlortetracycline or crown fungicide. Flower rot and cotton blight can be sprayed on the leaves with agents such as Kelu, Kojia, Anke, and Ridomil, or add some of the agents to the anthers.

3. Flower stigma rot. ⑴Symptoms: Black rot appears on the stigma of the flower, accompanied by the rot of the flower. ⑵Disease analysis: This may be caused by the lack of elements such as boron and calcium in the soil. It is also related to poor root absorption or uncoordinated water supply. ⑶Solution: Foliar fertilizers containing elements such as boron and calcium can be sprayed on the leaves, such as Green Fenwei No. 3 or No. 2, calcium nitrate, etc., or some calcium fertilizers can be flushed. At the same time, attention must be paid to root care to enhance the absorption capacity of the root system. Humic acid and microbial fertilizers can be added, or fast absorption can be flushed, or methyl thiophanate, bezoar, ethylene phosphate aluminum manganese zinc and other agents can be selected and then added to the rooting agent for root irrigation.
