Loofah price is very important
First, control the length of melons. The length of the melon is an important condition for the loofah to be welcomed by the vendor. Because there are certain restrictions on the type of packing box ordered by the vegetable purchaser, it makes them have a soft spot for the loofah that fits the length of the packing box. Take the Shouguang region as an example. Under normal circumstances, 40-50 cm long loofahs meet their requirements. To control the length of melons, you should do the following:
1. Choose the most important variety: Before choosing a variety, you should inspect the market and select the variety that suits the tastes of local farmers and consumers.
2. The concentration of dipping anthers has an influence: Usually, the concentration of dipping anthocyanins used is: 10 to 15 ml of fruit set, 8 ml of 2,4-D, and 15 ml of love, plus an appropriate amount of anti-dropping fruit and loofah. Jinshui. This concentration can ensure that the growth of melons is maintained at a normal level. Among them, the ability to influence the length of melons is the establishment of fruit and spirit, and 2,4-D. When these two agents are lower than normal doses, the melon strips will grow longer, and vice versa.
3. When the temperature in the greenhouse is between 27-30°C, the melon strips grow normally.
4, see the growth of the tree: If the tree too busy, you can stay more than a few melon to balance the nutrition, prevent the individual loofah due to excessive nutrition and "excess weight", on the contrary can be less to stay a few melons to ensure its adequate nutrition.
5, timely picking.
Second, adjust the melon straight and curved. In many books and newspapers, it is suggested that loofahs can be treated with hanging stones or hormone treatments if they are too curved during the young period. In fact, no need to do so, because loofah is very strong ability to sit melon, when the emergence of curved melon, it can be immediately removed, the next melon will quickly seize and rapid growth, will not have a significant impact on overall output.
Third, adjust the melon color. The color of the loofah epidermis depends on the species, but some external conditions also have some influence on it. To make the color of loofah bright, you should do the following:
(1) Prevent whitefly damage. Whitefly mainly sucks leaf sap, causing damage to the mesophyll, reducing leaf function, and subsequently affecting melon color. (2) Foliar application of multi-element fertilizers can effectively improve the color of melon strips. (3) Avoid shading caused by too much leaves, so that melon color is dull.
Fourth, the relations between melons and flowers. The loofahs on the market are now overhead flowers. How can the time of flowering be consistent with the harvest period of melon strips? There is also learning here:
(1) Excessive 2,4-D dose in dipping anthers will make flowers unopened after long forming, and the melon strips grow slowly. (2) Guayin is too dizzy with flowers, and the same phenomenon of “dumb flowers†​​that cannot be bloomed can also occur, and the melon strips grow slowly.
Therefore, it must be cautious and meticulous in the management of loofah flowering management to ensure that the melon strips can both grow fast and open at the same time when picking flowers. At the same time, it is necessary to prevent the loss of loofah. The cause of the burned-out loofah and its control measures are summed up as follows by Liu Chunxiang, vegetable expert of Shouguang Vegetable Association.
First, dry burnt flowers. (1) Symptoms: The edges of the petals are dry and dry, and the entire petals are not fresh. (2) Disease analysis: This may be the manifestation of the disease on the flowers. In the case of low light, heaviness occurs, especially after the cloudy days. (3) Solution: Thiomitraz or Dasheng or Shigong can be sprayed to reduce the occurrence of diseases.
Second, water burnt. (1) Symptoms: Water rot appears from the edge of the petal. In severe cases, the petal has symptoms of dripping, sometimes odor, and sometimes no, but white mold. (2) Disease analysis: The odor but not hairy condition may be a bacterial soft rot disease, and the Changbai mold may be a flower rot or a M. blight disease, both of which are heavy in the case of high temperature and high humidity. (3) Solution: Bacterial soft rot may be sprayed with streptomycin, neomycin, or sprayed with copper preparations such as chloramphenicol or chloramphenicol. Flower rot and Bacillus diseases can be sprayed with foliar sprays such as Kelu, Kejia, Anke, Lei Duomi, etc., or some of the medicaments can be added to the anthers.
Third, the head rot. (1) Symptoms: Black rots on the stigma of flowers, accompanied by flower rot. (2) Disease analysis: This may be due to the lack of diseases caused by lack of elements such as boron and calcium in the soil, but also related to poor root absorption or inconsistent water supply. (3) Solution: Foliar can be sprayed with foliar fertilizers containing boron, calcium and other elements, such as Green Fenway No. 3 or No. 2, calcium nitrate, etc., but also part of calcium fertilizer, but also pay attention to the rooting The absorption capacity of the root system can be increased by applying humic acid and microbial fertilizers, and can also be quickly absorbed by flushing, or by using thiophanate-methyl, hymexazol, phospha-aluminum manganese zinc, etc. .
