Problems solved by technology

[0003] However, the existing artificial cultivation techniques are not suitable for continuous planting on the same piece of land. Once planted for a long time, the nutritional quality of muskmelon will be low and the yield will be unstable.

Embodiment 1

[0015] The soilless cultivation method of kind high-sugar Hami melon of the present invention, comprises the steps:

[0016] a. Sowing and raising seedlings: Soak the seeds in warm water at 50-60°C for 2-3 hours, remove them and sterilize them with 0.1-0.2% potassium permanganate for 20 minutes, wash them with clean water, drain the water, wrap them in a damp cloth, and place them at a constant temperature Pregerminate in the box at 30-32°C, sow in dew, the water level in the tank is 1 / 2-2 / 3 of the planting cup, cover the foam board after sowing, open the board after germination, and use 1 / 4-1 / 5 of the nutrient solution Seedling cultivation, cycle 2 to 3 hours a day;

[0017] b. Planting: When the height of the seedlings is 3 to 4 leaves, they can be planted. For each planting board, put 4-6 seedlings. The water level of the tank is controlled at 1 / 3 of the bottom of the cup. Nutrient solution is used. The specification of the planting board is 1 ×1.5m;

[0018] c. Preparati...

Embodiment 2-9

[0023] Different from Example 1, the following examples have carried out a comparative experiment on the effect of the anti-cracking agent, specifically as shown in Table 1:

[0024]

Embodiment 10-17

[0026] Different from Example 1, the following examples have carried out a comparative experiment on the effect of temperature, specifically as shown in Table 2:

[0027]

[0028]

[0029] Table 2

[0030] The sweetness is measured by taking the cantaloupe obtained from each group and the cantaloupe obtained by the prior art, squeezing the juice respectively, taking the sweetness of the existing cantaloupe as 1, measuring multiple groups, and taking the average value.

[0031] By increasing the temperature difference between day and night in the greenhouse, the sweetness density of the cantaloupe growth gap can be increased, the natural light time during the day can be extended, and the ultraviolet light time in the greenhouse can be increased to achieve better sweetness of the southern cantaloupe. The anti-cracking liquid of the invention can increase the sweetness density of the Hami melon and reduce the fruit cracking rate.

Abstract

The invention discloses a soilless culture method for high-sugar Hami melons, which comprises the steps of sowing and seedling raising, planting, preparing nutrient solution, controlling temperature, pruning and leaving fruit, and the like, wherein the nutrient solution contains 20-50mg / kg gibberellin, 20-50g / kg sodium borate, 3-15g / kg monopotassium phosphate, 10-15mg / kg 6-benzyladenine, 30-50mg / kg brassin and 20-50mg / kg diethyl aminoethyl hexanoate; at different stages, the temperature control is as follows: the temperature is controlled at 18-22 DEG C at night and 25-30 DEG C in the daytime during the period from planting to surviving; the temperature is controlled at 15-20 DEG C at night and 28-35 DEG C in the daytime during the period from surviving to blooming; during a melon growing period, the temperature is controlled at 22-27 DEG C in the daytime and 15-18 DEG C at night, and an ultraviolet lamp is used for illuminating for 1-2 hours with the luminance being 1500-2000muW / cm<2>; and after the melon growing, the shed temperature is kept at 30-35 DEG C in the daytime and 15-18 DEG C at night, and the ultraviolet lamp is used for illuminating for 2-3 hours, with the luminance being 5-10mW / cm<2>. According to the method provided by the invention, the quality such as the sweetness of the Hami melons is increased, and meanwhile, the fruit cracking phenomenon is reduced.

Description

technical field [0001] The invention relates to crop cultivation, in particular to a soilless cultivation method for high-sugar Hami melon. Background technique [0002] Melon is also called sweet melon or muskmelon. Melon is named for its sweet taste, and it is also called muskmelon because of its delicate fragrance. Melon is a summer melon to cool off the summer heat, and its nutritional value is comparable to that of watermelon. According to the measurement, except that the content of water and protein in melon is lower than that of watermelon, other nutrients are not less than that of watermelon, while the content of aromatic substances, minerals, sugar and vitamin C is significantly higher than that of watermelon. Eating more melons is beneficial to the activities of the human heart, liver and intestinal system, and promotes endocrine and hematopoietic functions. Medicine has confirmed that melon has the remarkable effect of "relieving summer heat, relieving polydips...
