Cultivation techniques of cantaloupe in greenhouse

In recent years, cantaloupe has been successfully introduced, demonstrated and popularized in Jiading, and a number of cantaloupe varieties suitable for cultivation in the eastern region have been selected, among which Xuelihong has become the leading Hami melon variety in this area. At the same time, through the form of "base + farmers", cantaloupe has been promoted to the majority of farmers, and has formed a set of relatively mature cultivation techniques in greenhouse. The cultivation techniques in greenhouse are introduced as follows: first, the variety characteristics of Xuelihong, muskmelon bred by Hami Melon Research Center, is an early and middle mature variety, the fruit development period is about 40 days, the fruit is oval, the pericarp is white, and occasionally has sparse reticulation. White through red when ripe The flesh is light red, the meat is tender, crisp and refreshing, it melts in the mouth, tastes like fragrant pear, the central refractive sugar is more than 15%, and the single melon weighs about 2.5 kg. Second, the sowing date determines the best sowing time for spring greenhouse cultivation of Hami melon in Shanghai: from late January to early February. 3. Cultivate strong seedlings 1. The seeds can be treated by drying, and the dried seeds can be roasted in a 60-69 ℃ constant temperature drying box for about 3 days, and the disinfection and sterilization effect is good. If there is no such condition, the seeds can be dried in strong sunlight for 2 days. 2. When sowing and sowing, first, the bowl noodles should be flat, and the seedling bowls should be arranged closely; second, the seedling bed should be fully watered and sown after underwater infiltration; third, a bowl of seeds should be laid flat; third, the depth of covering soil should be the same, and the thickness should be about 1cm, and it should be gently compacted after sowing. 3. Seedling bed management emphasizes heat preservation and disease prevention in spring, the seedling bed is covered with multi-film, and the ground is covered with electric heating line. Temperature management: adopt the method of "two high and two low" to change the temperature, that is, before emergence, the temperature of the seedling bed should be kept at 30: 32 ℃ during the day and 18: 20 ℃ at night to promote the seedling; before the first true leaf is unfolded, the bed temperature should be appropriately reduced, between 25: 28 ℃ during the day and 15: 16 ℃ at night, to prevent tall seedlings. When the third true leaf appeared, the bed temperature should be properly increased, keeping it between 30-32 ℃ during the day and 18-20 ℃ at night, in order to promote early emergence of true leaf, and low temperature seedling refining was carried out one week before planting to make the seedlings gradually adapt to the field environment.
