Problems solved by technology

[0002] At present, the cultivation mode of purple lettuce is: using the traditional soil seedbed for seedling cultivation, land preparation for border cultivation, flood irrigation and watering, and manual trenching and hole digging for fertilization. The disadvantage is that it is easily affected by the environment. Unevenness, long seedling period after transplanting, poor leaf growth, easy to cause curling and deformity of leaves, and more diseased and rotted leaves in the later stage
It has adverse effects on the high-quality and high-efficiency cultivation of purple lettuce

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 seedlings of lettuce grow to "three leaves and one heart", they are transplanted to the field, with two rows per ridge, the spacing between plants is 27-30 cm, digging holes for planting, and cultivating the surrounding soil. , so that the substrate part is 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 co...

Abstract

An open-field high-quality and high-efficient cultivation technique of purple leaf lettuces is characterized by including soil preparation, ridging, seedling, transplanting for field planting, management and other processes. The open-field high-quality and high-efficient cultivation technique solves the problems of the traditional seasame cultivation mode of purple leaf lettuces that seedlings are irregular and uneven in size after seedling emergence due to environment implication, the rejuvenation period is long after transplanting, leaf plants fail to thrive, leaf curving and malformation are apt to occur, and the plants are susceptible to diseases and rotting in the later period; is applicable to open-field planting of purple leaf lettuces.

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 purple lettuce in the open field. Background technique [0002] At present, the cultivation mode of purple lettuce is: using the traditional soil seedbed for seedling cultivation, soil preparation for border cultivation, flood irrigation and watering, and manual trenching and hole digging for fertilization. Unevenness, long seedling period after transplanting, poor leaf growth, easy to cause curling and deformity of leaves, and more diseased and rotted leaves in the later stage. It has adverse effects on the high-quality and high-efficiency cultivation of purple lettuce. Contents of the invention [0003] In order to solve the technical problems existing in the traditional purple lettuce cultivation method, the invention invents a high-quality and high-efficiency cultivation technology of purple lettuce in the open f...
