Embodiment Construction

[0011] 1. Soil preparation and ridging: plow the ground first, then spread the basal fertilizer, then rotate the ground, raise the ridges, lay drip irrigation belts, and cover with plastic film. The height of the ridge is 16-20 cm, and the distance between the ridges is 85-90 cm;

[0012] 2. Seedling cultivation: Mix peat, vermiculite, and perlite in a ratio of 9-3-1 as the substrate, put the mixed substrate into a 128-hole tray, and put one seed in each hole, then put it in the smart greenhouse and set it up. nursery;

[0013] 3. Transplanting and planting: When the lettuce seedlings grow to "three leaves and one heart", transplant them to the field, double rows per ridge, plant spacing 27-30 cm, dig holes for planting, and cultivate the surrounding soil. The transplanting should not be too deep. Make the substrate part just level with the surface, and water the roots in time;

[0014] 4. Water and fertilizer management: maintain a certain amount of moisture (soil moisture c...

Abstract

A high-quality and high-efficiency cultivation technology for lettuces in an open field is characterized by comprising the processes of land preparation, ridging, seedling culture, transplantation, field planting, management and the like. The high-quality and high-efficiency cultivation technology solves the problems that the lettuces are easily influenced by the environment, seedling emergence and seedling sizes are uneven, the seedling recovery period is long after transplantation, leaves and plants grow badly, blades are prone to curling and deformation, and diseases and rotting are caused in a later period in a traditional cultivation and planting pattern. The high-quality and high-efficiency cultivation technology is suitable for planting of the lettuces in the open field.

Description

technical field [0001] The invention relates to the field of vegetable planting, in particular to a high-quality and high-efficiency cultivation technique of lettuce lettuce in the open field. Background technique [0002] At present, the cultivation mode of lettuce is: using traditional soil seedbed for seedling cultivation, soil preparation for border cultivation, flood irrigation and watering, artificial ditch digging and hole fertilization management mode. Uniformity, long seedling period after transplanting, poor leaf growth, easy to cause curling and deformity of leaves, and many diseases and rots in the later stage. It has adverse effects on the high-quality and high-efficiency cultivation of lettuce. Contents of the invention [0003] In order to solve the technical problems existing in the traditional lettuce cultivation method, the invention invents a high-quality and high-efficiency cultivation technology of lettuce in the open field. [0004] Technical scheme...
