When the Spring Festival is over, it is about to start spring. At this time, many farmers are prepared to sow loofah, but many farmers are worried that they will encounter loofah, which is the problem of melon. In fact, loofah melon is a phenomenon that can not continue to grow after the formation of juveniles, and the phenomenon of yellowing and shedding, which is also a common phenomenon in the growth process of melon crops. So why do you have loofah melons? How to prevent them? How to remedy them? 1. Reasons for loofah melon (1) There is no good seedling: after planting the seedlings, there is no timely control of the seedlings to promote the roots, premature topdressing and watering. (2) Colonization is too dense: the planting density is too large, and the ventilation and light transmission between the plant population is poor. (3) The temperature is too high: the ambient temperature is high, especially the night temperature is high, or the temperature difference between day and night is small, or the light is insufficient. (4) Poor pollination: If there are fewer pollinators in the low temperature season (planting in greenhouses), or less male flowers, or low pollination rate, it will also cause the emergence of melons. (5) Insufficient water and fertilizer: lack of water and fertilizer in the melon period, etc., will induce the melon. 2, preventive measures for loofah (1) Reasonable close planting According to the planting season, cultivation methods, soil fertility, variety and melon pattern, choose the appropriate planting density. The early maturing varieties are recommended to be 500-200 per acre, and the medium-maturing varieties are cut to 600-800, which can be planted in the daily greenhouse. 3500-4000 beads. (2) Appropriate seedlings Before planting and slowing down the seedlings, before controlling the flowering and melons, properly control the watering and fertilization, timely cultivating and weeding, and adopting the measures of heat preservation or cooling according to the planting season to promote the normal growth of the seedlings. (3) Strengthen plant management Timely scaffolding or hanging vines, pruning in the sunny afternoon (weak side branches and excess side branches), so that the stems are evenly distributed, remove male flowers, tendrils and lower yellowing leaves, and timely topping. (4) Timely topdressing and watering After entering the melon period, generally 1 or 2 times of topdressing per harvest, each time you can apply 300-600 kg of decomposed manure, or 10-15 kg of urea, or apply nitrogen, phosphorus and potassium compound fertilizer at intervals. 10-15 kg. See the balance of watering (watering in the hot season should be in the morning and evening), try to stabilize the soil moisture and temperature, to avoid the phenomenon of physiological dryness or drought and humidity. Take measures to maintain proper temperature and light, avoiding night temperatures below 13 degrees, or long-term higher than 30 degrees during the day. Carbon dioxide fertilization techniques can be used as appropriate in protected areas. (5) Artificial pollination or plant growth regulator Protected cultivation, it is advisable to take the newly opened male flowers in the evening or in the morning without dew. After removing the petals, apply the pollen to the stigma of the female flower petals. Do not damage the stigma and ovary. It can also be applied with 2, 4 drops of 10~30 mg/L (蘸) flowers (required before use). (6) Picking melons in time 10-12 days after the pollination of the loofah, the harvest is selected before the morning, and the melon period can be harvested once a day. Use scissors to cut at the handle of the fruit to prevent the melon from being scratched. 3, remedies for loofah melon (1) Take measures to symptomatic, according to the factors that induce the melon, use specific measures such as adjusting the ambient temperature and light, or topdressing watering, or pruning and leafing, or artificial pollination. (2) Remove the melon, and remove the dried melon strips as soon as possible. The above is the cause of loofah melon and preventive and remedial measures. Only by mastering the above prevention and remedial measures can farmers avoid the phenomenon of loofah as soon as possible. If the farmers do not pay attention, it will seriously affect the yield and quality of loofah.
