Problems solved by technology

[0002] At present, the cultivation mode of head lettuce is: using the traditional soil seedbed for seedling cultivation, soil preparation for border cultivation, flood irrigation and watering, manual ditch digging and fertilization management mode. Unevenness, long seedling period after transplanting, poor growth of leaf balls, easy to cause curling and deformity of leaves, no balling, easy bolting in the early stage, and diseased and rotted leaves in the later stage
It has adverse effects on high-quality and high-efficiency cultivation of head 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 lettuce seedlings grow to "three leaves and one heart", they are transplanted to the field, with two rows per ridge, and the plant spacing is 27-30 cm. Dig holes for planting, and cultivate the surrounding soil. 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 content 65-75%), and use d...

Abstract

The invention discloses a high-quality and efficient open field culture technology for head lettuces. The technology is characterized by comprising the processes of land preparation, ridging, seedling culturing, transplantation and colonization, management and the like. According to the technology, the problems of high environmental impact rate, irregular seedling emergence, seedling non-uniformity, long growth delaying period after transplantation, poor growth of heads, high curling deformity rate of leaves, no head wrapping, high bolting rate in an early stage and high disease and rotting rate in a later stage of the head lettuces under a conventional culture mode are solved, and the technology is applied to the open field culture of the head lettuces.

Description

technical field [0001] The invention relates to the field of vegetable planting, in particular to a method for cultivating head lettuce. Background technique [0002] At present, the cultivation mode of head lettuce is: using the traditional soil seedbed for seedling cultivation, soil preparation for border cultivation, flood irrigation and watering, manual ditch digging and fertilization management mode. Unevenness, long seedling period after transplanting, poor growth of leaf balls, easy to cause curled and deformed leaves, no balls, easy bolting in the early stage, and diseased and rotted leaves in the later stage. It has adverse effects on high-quality and high-efficiency cultivation of head lettuce. Contents of the invention [0003] In order to solve the technical problems existing in the traditional head lettuce cultivation method, the invention invents a high-quality and high-efficiency cultivation technology of head lettuce in the open field. [0004] Technical ...
