Xia Shougua has a high economic benefit, and its cultivation and management are different from those of spring and autumn loofah. It is prone to the phenomenon of vine-leafing, slow flowering, and so on. The cultivation should pay attention to the following issues:
First, choose a good species
The varieties that are suitable for summer cultivation are varieties that are insensitive to short days, such as Xia Yugua, Xin Xia Loofah, Feng Kang Loofah, Yalu No. 1, Xiu Yu Loofah and so on.
Second, nursery transplanting
Summer loofah should not be broadcast live, should choose well-drained field seedling transplant. The loofah seeds were soaked in fresh water for 8 to 10 hours, picked up and drained for sowing. Seeding methods are commonly used plastic nutrient cups and nursery tray seedlings, nutrient soil should be used in new soil or vegetable garden soil not planted melons. Sow 1 seed per hole when planting. Before transplanting seedlings, it is necessary to properly control water and fertilizer and cultivate strong seedlings. When seedlings have 2 to 3 true leaves, they can be transplanted into Daejeon.
Three, field selection
Loofah like fertilizer, soil fertility should be selected, high organic matter content, water and fertilizer holding capacity of the loam field cultivation.
IV. Site preparation
1. Land preparation. Cultivated plants are planted with a width of 1.2 to 1.5 meters, a width of 30 to 40 centimeters, and a height of 35 centimeters. Combined with site preparation for basal fertilization, Mushi soil mixed fertilizer 2000 kg, compound fertilizer 50 kg.
2. Colonization. Xia Shougua cultivation planting row spacing is 70 cm to 80 cm 50 cm, about 1700 per mu suitable.
V. Field Management
1. vine leaf finishing. In general, the first vine is crushed for about 35 centimeters in length, and the second time it is crushed about 70 centimeters in length. The vine pressure method depends on the weather conditions. In sunny days, a small ditch is opened and the vines are pressed into the ditch and then covered with small clods. In the rainy days, the vines are pressed on the surface of the vine, and the ditch is not opened to prevent rot of the stalks. In case of continuous rain, When the area is water, it is only necessary to press the blade with a piece of mud, not to press the stem, and also to fix the roots of the stem to prevent the stem from rot. Xia Suangua is vine-grown and generally attracts vines when it emerges. Zigzag draws evenly. In the late growth stage, the old leaves or diseased leaves of the base are properly removed. In the case of overgrowth of vine leaves, some of the leaves may be removed at different intervals in the upper, middle, and lower parts, or the leaves may be picked when the vine leaves grow too densely. , conducive to air and light or reduce pests and diseases.
2 timely management melon. During the flowering period, when it was found that the small melons were resting on the leaves, racks, melon vines, or tendrils, they needed to be sorted out in a timely manner so that they could be suspended vertically in the scaffolds, and the diseased melons should be removed to prevent infectious diseases.
3. Reasonable fertilization. The general principle of fertilization is: diligent application of thin application, control of water and fertilizer before the squash, after squash and lateral vine spread when applying heavy fertilizer, and pay attention to the application of phosphorus and potassium fertilizer. Should apply enough organic fertilizer, suitable for chemical fertilizers. The organic fertilizer is full, and the loofah grows straight and long, otherwise it may cause malformations. 5 to 7 days after transplanting, mu was applied with 1,500 kg of 1:10 diluted feces and urine water to promote the growth of stems and leaves. Fertilizer depends on seedling conditions until flowering results: seedlings grow vigorously, dark green, you can apply less or no fertilizer; grow weak, every 15 days per acre applied 4 to 6 kg of compound fertilizer leaching solution 1500 kg. After the results, the fertilizer was applied once every 5 to 7 days, and each application of compound fertilizer was 10 to 15 kilograms per mu. The amount of fertilization during the harvesting period should be increased by 1 to 2 times, and 1 to 2 times of plant ash should be added. 50 to 100 kg.
4. Moisture management. Loofahs need more water during the whole growth period, and should keep the soil moist in the early stage of growth. The water needs to be the most during the period of flowering and fruiting of the plants, and the root system is also strong. The irrigation needs to be strengthened. Luffa not only need water, but also avoid accumulation of water, when the irrigation should be immediately irrigation, row, not flood irrigation, especially in the rain, it should pay attention to drainage, in order to prevent the area of ​​water.
