Problems solved by technology

[0002] At present, the cultivation mode of red lettuce is: using traditional soil seedbed for seedling cultivation, land preparation for border cultivation, flood irrigation and watering, artificial ditch digging and fertilization management mode. 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 lettuce

Embodiment Construction

[0011] 1. Land preparation and ridging: first turn the ground, then spread the base fertilizer, then rotate the ground, ridge, spread drip irrigation tape, and cover with mulch, the ridge height is 16-20 cm, and the ridge spacing 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 plug tray, with one seed per hole, and then put it in the smart greenhouse. Nursery

[0013] 3. Transplanting and colonization: When the red oil lettuce seedlings grow to "three leaves and one heart", they are transplanted to the field, with double rows in each ridge, planting 27-30 cm apart, digging holes for colonization, and cultivating the surrounding soil. Transplanting should not be too deep , Make the substrate part just level with the ground, and pour root water in time;

[0014] 4. Water and fertilizer management: maintain a certain moisture content (soil water content 65-75%), use drip irri...

Abstract

The invention discloses a cultivation technology of red Lactuca sativa L. The cultivation technology is characterized by comprising the steps of land preparation, ridging, seedling growing, transplanting in a field, managing and the like. The problems are solved that in a traditional cultivating and planting mode, red Lactuca sativa L. is easily influenced by the environment, germinated seedlingsare not neat, seedlings are not uniform in size, after transplanting, the rejuvenation period is long, leaf plants suffer from undergrowth, and curling and deformation of leaves are easily caused, andred Lactuca sativa L. is susceptible to diseases and rotting in the later period. The cultivation technology is suitable for planting red Lactuca sativa L. in open fields.

Description

Technical field [0001] The invention relates to the field of vegetable planting, in particular to the cultivation technology of red oil lettuce. Background technique [0002] At present, the cultivation mode of red oil lettuce is as follows: the traditional soil seedbed for seedling cultivation, land preparation for border cultivation, flood irrigation and watering, artificial ditching and hole digging and fertilization management mode. Its disadvantage is that it is easy to be affected by the environment. Uneven, slow seedling period is long after transplanting, and poor growth of leaf plants is easy to cause leaf curling and deformity, and diseased rot in the later stage. It has adverse effects on the high-quality and high-efficiency cultivation of red oil lettuce. Summary of the invention [0003] In order to solve the technical problems existing in the traditional red oil lettuce cultivation method, the invention invents the red oil lettuce cultivation technology. [0004] The...
