1 Cultivate strong seedlings: The open field cultivation is divided into two types: cultivation with brackets and climbing cultivation. It is possible to select good varieties with strong growth potential, large stems and leaves, and high resistance to heat, alfalfa, drought, and disease resistance. For example, early-maturing varieties include a series of bells, swarms of bees, five leaves, Jilin small melons, and white husks. , Neijiang, Datoutou winter melon, late-maturing varieties such as Daqingpi, Hunan vermicelli, Yangzizhou, White Peel, etc. can be broadcast live or transplanted. Seeds are first soaked with 0.1-0.2% potassium permanganate solution for 30 minutes, rinsed with clean water and then soaked in hot water at 50-60°C. Continue stirring until the water temperature drops to about 30°C. Continue soaking 12-14 hours, remove at 30-35°C
Under heat preservation germination.
Seeding and seedling cultivation methods can be divided into seedling seeding method and seedling seeding method. Sub-seed sowing method, seedlings on the seedbed, seedling spacing 2-4 cm, when the first true leaves can be divided into seedlings, seedlings can be planted when 4 leaves 1 heart. Regardless of seedling seeding method, that is no longer divided seedling after sowing, grown in situ suitable for planting strong seedlings, generally used for late sowing, high temperature, fast growth, short-term seedlings of late-maturing melon seedlings.
2 heavy basal fertilizer, timely planting: melon production is high, the amount of fertilizer required, to obtain high quality and high yield, must be sufficient base fertilizer, rich in nitrogen, phosphorus, potassium and other nutrients of organic fertilizer-based. When planting or doing earthworms at the time of site preparation, it will be 75,000 to 105,000 kilograms per hectare. If the source of organic fertilizer is insufficient, the nitrogen, phosphorus, and potassium compound fertilizer applied in the ditch or hole will be 750-1050 kg per hectare when planting. After the end of the frost in the northern region can be planted. Generally, there were 82,500 strains of early melon melons, 21,000-2.55 strains of middle-season melon, and 15,000-18,000 strains of late-maturing wax gourd.
3 skillfully applied topdressing, Zhuang Zang remind melon: after 1 week of planting, when the plants began to slow seedlings, the seedlings could be poured. If basal deficiencies are insufficient, the fertilizer can be applied lightly after easing the seedlings. When the melon is stable, he must chase and apply the “guarantee melon fertilizer†in time. This fertilizer is the key to the high yield and quality of wax gourd. It can be used as a combination of pouring "water to accumulate melons" and applying diluted fecal urine (10 times) or 15,000 kg/ha of cake fertilizer per hectare. After topdressing “guarantee melonâ€, the fertilizer should be topdressed every 15 days or so, and the best one should be based on the growth of melons and soil drought. The period of fruit enlargement is the period when the wax gourd plants need fertilizer and water, and it is also a crucial period for determining the level of yield. This period should be combined with watering in a timely manner, increase the amount of topdressing, each time after each hectare topped with diluted manure fertilizer or thin cake fertilizer 22500 kg / ha or so, you can also follow the application of ternary compound fertilizer 750 kg / ha. During the fruit ripening period, it is generally necessary to have a small amount of fertilizer, and the management is mainly focused on eliminating sputum, preventing disease, and controlling pests. In order to prevent premature aging, suitable amounts of humic acid fertilizers can be sprayed to extend the result period. No longer fertilize 10-15 days before harvest. Generally early-maturing varieties and some mid-maturing varieties, first picking the tender cucumbers on the market, and finally harvesting the old ripe melons can be stored in the warehouse and extend the supply period. Most of the late-maturing varieties harvested the old ripe melon, which is the standard of physiological maturity, in order to improve its resistance to storage and transportation.

A hydrogen inhaler is a device that delivers hydrogen gas for inhalation. Hydrogen gas is considered to have potential health benefits due to its antioxidant and anti-inflammatory properties. The inhaler typically contains a chamber that generates hydrogen gas by electrolysis of water or by using hydrogen-rich tablets or cartridges. When the user inhales through the device, they can potentially benefit from the therapeutic effects of hydrogen gas. Some claimed benefits of hydrogen inhalation include reducing oxidative stress, inflammation, and improving athletic performance. However, further research is needed to fully understand the potential benefits and risks associated with hydrogen inhalation. It is important to consult a healthcare professional before using any new health device or treatment.
