Simplified cultivating method for dry-cure pepper

The invention discloses a simplified cultivating method for dry-cure pepper. The method improves the emergence rate, the planting percent and the strong seedling rate of direct-seeded seeds of pepper by covering and using direct-seeding nutrition balls and direct-seeding nutrition matrix. The method furhter solves the problems that surface layers in field direct seeding is prone to hardening due to the fact that soil temperature and humidity are affected by environment to be large in change to be unfavorable for seed emergence of pepper seeds and growth of seedlings. In addition, the method achieves practicability of pepper direct-seeding techniques and widens popularization and application ranges. By means of black film covering and direct seeding cultivation, the problems of weed growth in fields and serious pepper lodging are effectively solved, minimal tillage or zero tillage in fields are achieved, the use of weed killers is reduced, specific fertilizers are screened through tests to solve the problem of one-time fertilization in pepper production, additional fertilizers are avoided in pepper production on the premise of avoiding output reduction of peppers, and the problem of harvesting dry-cure scatter and fresh peppers at one time in a concentrated mode is solved. Thus, the purposes of achieving low cost production of peppers and improving pepper quality are achieved.
