Problems solved by technology

[0002] At present, the lettuce cultivation mode is: the traditional soil seedbed seedling cultivation, land preparation for border cultivation, flood irrigation and watering, manual ditch digging and fertilization management mode, the disadvantage is that it is easily affected by the environment, uneven seedling emergence, and uneven seedling size After transplanting, the slow seedling period is long, and the leaves grow poorly, which can easily cause curling and deformity of the leaves, without balling, easy bolting in the early stage, and diseased rot in the later stage
Adverse effects on high-quality and high-efficiency cultivation of 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%), use drip ...

Abstract

The invention relates to an open-field, high-quality and efficient cultivation technology for lettuce. The technology is characterized by comprising the processes of carrying out soil preparation, ridging, carrying out seedling culture, carrying out transplanting and field planting, managing and the like. According to the technology, the problems of the lettuce that in the traditional cultivation and planting mode, the lettuce is prone to environmental influence and is subjected to irregular seedling emergence and non-uniform seedling size, the seedling delaying period is long after the lettuce is transplanted, the growth of leaf plants is poor, and then, curled and deformed leaves and late-stage sickliness and rot are easily caused are solved; the technology is applicable to the open-field planting of the lettuce.

Description

technical field [0001] The invention relates to the field of vegetable planting, in particular to a high-quality and high-efficiency cultivation technique for lettuce in the open field. Background technique [0002] At present, the cultivation mode of lettuce is: using the traditional soil seedbed for seedling cultivation, soil preparation for border cultivation, flood irrigation and watering, artificial ditch digging and fertilization management mode. , after transplanting, the slow seedling period is long, and the leaf growth is poor, which can easily cause curling and deformity of the leaves, no balling, easy bolting in the early stage, and diseased and rotted leaves 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...
