The ripening time of loofah is generally around September every year, that is, autumn. Luffa takes about 4 months to germinate, but it will bloom after germination, and the time from flowering to fruiting is very short. It takes 20-25 days from budding to rooting, and lasts about 50-60 days after entering the full fruit stage.
Management technology of loofah planting
1, planting time
The sowing time of loofah is generally in March in spring, June-July before autumn, and can only be sown after Qingming in cold areas. Seedlings can be planted first and then transplanted in early spring. If the temperature rises to a stable temperature above 15℃, direct broadcast can be used before autumn.
2. Seed treatment
Before sowing, dry the seeds for 2 days and put them in warm water at 50℃ and stir them evenly. If you have potassium permanganate at home, you can add 1g to the water for disinfection. After 30 minutes, take out the seeds and wash them, then soak them in warm water at 30℃ 12 hours. After the seeds have absorbed enough water, they can be sown.
3. Sowing and raising seedlings
Luffa can be broadcast live, and live broadcast is relatively simple. First of all, we should tidy up the ground in advance, dig holes and sow as needed, and sow 2 seeds in each hole. After the seeds emerge, the seedlings should be thinned and a strong silk seedling should be left in each hole.
You can also raise seedlings before transplanting and planting. When the temperature is lower than 15℃ in spring, cover with plastic film to keep warm and moist. When the temperature is higher than 25℃, you need to take a breath of fresh air, and the water demand is small during seedling raising. When the soil is dry and watered, the seedling age is about 30 days.
3. Fine soil preparation
Choose melon crops that have not been planted for two years. One month in advance, the soil should be turned 20 cm deep, which can kill the germs contained in the soil, prevent future diseases and improve the porosity and fertility of the soil.
A week before planting, the soil was carefully prepared again, and 4000 kg of decomposed farm manure, 60 kg of cake fertilizer and 50 kg of calcium superphosphate were put into each mu. Sow all the fertilizers into the soil evenly, and level them with agricultural machinery to make a plot with a ridge width of 1.5m, a ditch width of 0.5m and a ditch depth of 0.25m.. ..
4. Transplanting and planting
When the growth height of towel gourd seedlings is 15-20 cm, it can be transplanted to the field for field planting. In spring, the temperature should be 18℃, and one row should be planted on both sides of the plot, with a width of 1.5 m, one plant in each hole with a spacing of 40 cm and a middle interval of 1. 1 m, and one plant in each acre. When raising seedlings, the roots should be covered with soil, so as to avoid throwing soil and hurting the roots. After planting, water the roots once and then lightly.
5. Tian Tuan management
When the seedlings are 50 cm long after the melon seeds are planted stably, it is best to set up a shed to pull vines, preferably after 5 pm. At the same time, loofah should also be loosened and weeded for 2-3 times.
After the growth is stable after planting, topdressing should be done 2-3 times in the whole growth cycle.
Luffa needs pruning, leaf thinning and ventilation during its growth. Generally, the lateral plants below 80 cm are cut off, and when the growth length reaches 3 meters, they are capped, so that many lateral vines and sunny vines can grow. It is found that vines that bloom and fail to bear fruit should be cut off, and the old leaves, diseased leaves and yellow leaves under the roots should be removed.
