Problems solved by technology

[0003] In the current planting technology, lettuce has poor growth, low survival rate, and is prone to diseases and insect pests in the current planting technology, resulting in reduced production and increased planting costs. The reason for this is that the soil for planting lettuce is not sufficiently nutritious and the fertility of the fertilizer used is not long enough. length, which in turn affects the quality and nutritional value of lettuce

Abstract

The invention discloses an Asparagus lettuce planting method. The Asparagus lettuce planting method comprises the following steps: (1) selecting a variety, (2) determining a sowing date, (3) cultivating strong seedlings, (4) performing final planting and management, and (5) controlling pests and diseases. According to the change of seasons, Asparagus lettuce of different varieties is selected forplanting, a reasonable time is selected for sowing, and a high survival rate and a good growth trend are achieved; and sufficient growth nutrients are provided through adoption of self-made decomposedorganic fertilizer for planting, and through reasonable management and alternate use of pest controlling chemicals, the control effect of pests and diseases is improved, and the quality and yield ofAsparagus lettuce are improved.
