specific Embodiment approach 1

[0007] Specific implementation mode one: the accompanying cultivation method for overcoming cucumber continuous cropping obstacles in this embodiment is realized according to the following steps: 1. plant cucumbers; After the associated crop grows to 20-25cm, the above-ground part of the associated crop is cut off; 4. Repeat the operation step 3 for 2-3 times, then stop the cutting, and continue to cultivate until the cucumber matures; wherein the associated crop in step 2 is wheat, oats, vetch or clover; step The sowing rate of secondary crops is 40-50g / m 2 .

[0008] In step one of the present embodiment, cucumbers are planted according to conventional methods.

[0009] After the cutting is terminated in Step 4 of this embodiment, the accompanying species will continue to grow.

specific Embodiment approach 2

[0010] Embodiment 2: This embodiment differs from Embodiment 1 in that the number of days for planting cucumbers in step 2 is 3 to 5 days. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0011] Specific embodiment three: the difference between this embodiment and specific embodiment one is that the number of days for planting cucumbers in step two is 4 days. Other steps and parameters are the same as those in Embodiment 1.

Abstract

The invention discloses an accompanied cultivation method for overcoming obstacles to continuous cropping of cucumber and solves the problems of poor prevention and cure effect of chemical agents, environment pollution and generation of resistance to chemical caused by obstacles to continuous cropping of cucumber. The method comprises the following steps) planting cucumber seedlings; 2) sowing seeds of companion crop besides the cucumber seedlings; 3) removing overground parts of the companion crop; and 4) repeating the step 2 and the step 3, stopping removing the overground parts of the companion crop and cultivating the cucumber seedlings till cucumbers become rip. The accompanied cultivation method for overcoming obstacles to continuous cropping of cucumber reduces obstacles of soil to continuous cropping of cucumber and use of agricultural chemical, avoids environmental pollution and generation of resistance to chemical and provides an effective technical guarantee for production of green vegetables.

Description

technical field [0001] The invention relates to a method for overcoming obstacles in cucumber continuous cropping. Background technique [0002] Nowadays, cucumber cultivation has developed rapidly, accounting for more than 60% of the total vegetable cultivation area, and has become the main type of vegetable cultivation; due to its large cultivation area and large annual market demand, continuous cropping is very common, and because cucumbers are not resistant to continuous cropping, Therefore, continuous cropping obstacles of cucumber are very serious in production, and the output and quality are all greatly reduced. At present, chemical pesticides are often used to prevent and control cucumber continuous cropping obstacles, but the control effect is poor, and because of the long-term use of chemical pesticides in large quantities, pathogenic bacteria have developed drug resistance, which will gradually accumulate a large amount of pesticides in the environment, especially...
