Problems solved by technology

[0002] At present, the lettuce cultivation mode in the Netherlands 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. Uniformity, long seedling period after transplanting, poor growth of leaf balls, easy to cause curled and deformed leaves, no balls, diseased and rotted in the early and late stages

Embodiment Construction

[0011] 1. Soil preparation and ridge formation: plow the ground first, then spread base fertilizer, then rotate the ground, form ridges, lay drip irrigation belts, and cover with plastic film. The height of the ridge is 17-22 cm, and the distance between the ridges is 90-100 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 i...

Abstract

The invention provides a planting technology of Dutch lettuce. The planting technology is characterized by including the processes of soil preparation, ridging, seedling raising, transplanting and field planting, management and the like. The problems that in a traditional cultivating and planting mode, cauliflowers are easily affected by the environment, seedlings emerge disorderly, large seedlings and small seedlings are non-uniform, the rejuvenation period after transplanting is long, heads grow poorly, leaves easily curl and deform, head wrapping is not formed, and the cauliflowers are susceptible to diseases and rot in the early and later periods are solved, and the planting technology is suitable for open field planting of broccoli.

Description

technical field [0001] The invention relates to the field of vegetable planting, in particular to a technique for planting Dutch lettuce. Background technique [0002] At present, the lettuce cultivation mode in the Netherlands is: using the traditional soil seedbed for seedling cultivation, land preparation for border cultivation, flood irrigation and watering, and artificial trenching and hole digging for fertilization. The disadvantage is that it is easily affected by the environment. Uniformity, long seedling period after transplanting, poor growth of leaf balls, easy to cause curled and deformed leaves, no balls, and many diseases and rots in the early and late stages. It has adverse effects on the high-quality and high-efficiency cultivation of Dutch lettuce. Contents of the invention [0003] The invention aims to solve the technical problems existing in the traditional dutch lettuce cultivation method, and invents a dutch lettuce cultivation technique. [0004] T...
