During the cultivation of summer loofah, there are problems such as long leaves and slow flowering. In order to cultivate summer loofah, field management should be strengthened to promote the normal growth and development of plants.
1, vine leaves finishing
The main vines and side vines of summer loofah grow rapidly and vigorously. The result period is longer, requiring more nutrients and water. In plant adjustment, we must focus on the work of pressing and vine. By pressing the vine, it promotes adventitious roots, enlarges the root system, increases the ability to absorb nutrients and water, and ensures the nutrient and water needs of the vine leaves and flowering results. Generally, the first time the vine is carried out at a length of about 35 cm, and the second vine is carried out at a length of about 70 cm, and the vine can be led to the same direction or relative direction.
The method of pressing vines depends on the weather conditions. Open the small ditch on sunny days, press the melons into the ditch, and then cover the small clods; in the rainy days, press the vines on the clams, and do not open the ditch to prevent the stems from roting; continuous rain, 畦When the water is in the area, it is only necessary to press the leaves with the mud block, and the stems and vines are not pressed, and the roots of the stems can also be fixed. When the vines are fenced, in order to adapt to the characteristics of the long and long stalks of the summer stalks, it is generally only when the male flowers appear, the vines are fenced, and the stalks are uniformly introduced after the fence.
In the middle and late growth stages, the old leaves or diseased leaves of the base are properly removed. When the vine leaves are too prosperous, some leaves can be removed at different parts of the upper, middle and lower parts, or the leaves can be picked at a position where the vine leaves are too densely grown. It is good for ventilation and light transmission and reduces pests and diseases.
2, timely management
During the flowering result, if the melon is found resting on the leaf, on the fence, between the melons and the vines, it should be arranged in time to be vertically suspended in the scaffold, and the diseased melon should be removed to avoid infectious diseases.
When the loofah melon is entangled by bamboo, leaves, vines or tendrils, it can not naturally sag and grow normally, and it is easy to bend or deform. It is necessary to carry the squash and the squash. Generally, the squash is carried out 2 to 3 days after the melon is formed.
3. Rational fertilization
In the summer cultivation, the seedling stage should control the fertilizer to control the water, and the female buds begin to topdress. The fertilizer is mainly based on organic fertilizer, and the fertilizer is applied in an appropriate amount. After 5 to 7 days of transplanting, 1,500 kg of 1:10 faecal urinary water was applied to promote stem and leaf growth. After the flowering results, the fertilization depends on the seedlings: the seedlings are strong and green, and they can be applied less or not; the growth is weak, and 4 to 6 kg of compound fertilizer leachate is applied per 1,500 or so per 1500 kg or 1: 10 faint urinary water 1500 kg. After the results, the fertilizer should be applied once every 5 to 7 days, and 10 to 15 kg of compound fertilizer should be applied per mu. During the harvest period, the amount of fertilizer should be increased by 1 to 2 times, and 1 to 2 times of planting ash should be applied 50 to 100 kg.
In the hot summer, water is needed early and late, the water is insufficient, the loofah is easy to fibrillate, and the quality is degraded. In the initial harvest period, 50 kg of wool fertilizer and 750 kg of pig manure are applied per acre. The harvesting period should be followed up in a timely manner. Generally, each harvest is 2 to 3 times, and the topdressing is once, each time 20 mu of imported compound fertilizer per acre, 10 kg of potash During the harvest period, the compound fertilizer water is sprayed once every other day, and the dosage is 2 kg per mu.
4, water management
Loofah requires more water during the whole growth period. The soil should be kept moist in the early growth stage. During the flowering period, the water needs most, and the root water absorption capacity is also strong. It is necessary to strengthen irrigation. Loofah requires both water and stagnant water. When filling, it should be irrigated and not flooded. Especially in rainy days, it should be drained to prevent water from smashing.
5, timely harvest
The loofah is about 10 to 12 days from flowering to commercial maturity. The harvesting standard, the body is full and well-proportioned, the fruit handle is smooth, the body is slightly hard, the skin has a soft feeling and no smoothness, and the shaking of the tail of the hand grip has a sense of vibration. The fruit should be kept intact when picking.
