As can be seen from Table 1, the plant height, stem thickness and maximum leaf area of the kylin melons obtained by the first two continuous cropping resistant cultivation methods of the invention reach higher levels in the field planting period of 1-3 weeks, and compared with the method adopting common compound fertilizers (comparative example 1), the kylin melons have better quality and higher yield; the feed additive is biological microbial inoculum fertilizer, biological bacteria fertilizer liquid, fruit fertilizer and the like in the cultivation process, so that not only are necessary nutrient substances provided for the growth and development of the kylin melons and the growth of the kylin melons promoted, but also the biological control effect is achieved, wherein the added trichoderma harzianum powder and the like effectively inhibit pests and pathogenic bacteria in soil, so that the adverse effects of blight, aphids and the like on the growth of the kylin melons are avoided, and the excellent-quality kylin melons are obtained. The single fruit of the kylin melon obtained by the method is heavier, the first batch of the kylin melon can reach more than 3.8kg, the highest central sugar content can reach 13.3 percent, and the planting level of the kylin melon is obviously higher than that of the traditional kylin melon.

While the present invention has been described in detail with reference to the specific embodiments thereof, it should not be construed as limited by the scope of the present patent. Various modifications and changes may be made by those skilled in the art without inventive step within the scope of the appended claims.

Claims

1. A continuous cropping resistant cultivation method for kylin melons is characterized by comprising the following steps:

2. The method for cultivating kylin melons as claimed in claim 1, wherein in step (1), the nutrient soil is sprayed with a solution of 30-50 vt% formalin diluted with water to 100-120 times and disinfected before sowing.

3. The method for cultivating kylin melons in accordance with claim 1 or 2, wherein in step (1), the nutrient soil is prepared by the following method: uniformly mixing plant ash, diatomite, farmyard manure, wheat bran and unseeded garden soil, and then adding water until the water content is 10-30% to obtain nutrient soil; the mass ratio of the plant ash to the diatomite to the farmyard manure to the wheat bran to the non-sown garden soil is 2-3:2-3:5-6:3-5: 3-6.

4. The method for continuous cropping-resistant cultivation of kylin melons as claimed in claim 3, wherein the mass ratio of plant ash, diatomite, farmyard manure, wheat bran and non-sown garden soil is 2:3:5:4: 5.
