Lettuce is best grown in the soil with high humus content and mixed evenly with rotten leaf soil and garden soil. This fertile and deep soil rich in organic matter, water and fertilizer conservation and convenient drainage and irrigation can make lettuce grow better and improve its yield and quality. Soil acidity and alkalinity also affect the development of lettuce. Because lettuce is more suitable for planting in acidic soil, the soil pH value should be stable between 5-7. 1、 What kind of soil is better for lettuce? 1. Fertile and deep: fertile and deep soil can promote the growth and development of lettuce. Moreover, such soil has strong water and fertilizer holding capacity, which can improve the utilization efficiency of fertilizer and save cost.
2. Loose and breathable: loose soil with uniform particles has less resistance, which is more conducive to lettuce seed germination. And the roots of lettuce can better extend and develop in such soil and provide more nutrients for the growth of leaves.
3. Good drainage: lettuce has developed roots and likes wet soil, but the soil cannot accumulate water during seed germination in the early stage of growth. Otherwise, the seeds may rot and die because there is no oxygen, resulting in the reduction of seedling emergence rate. 2、 What kind of fertilizer is better for growing lettuce 1. Base fertilizer: organic fertilizer, especially rotten farm fertilizer, is more suitable as the base fertilizer for planting lettuce. Although the effect of farmyard fertilizer is relatively slow, it contains many kinds of organic matter and long fertility duration.
2. Topdressing: lettuce is mainly added with nitrogen, phosphorus and potassium fertilizers, and the proportion of addition is also different in different periods. Nitrogen fertilizer is mainly needed in the seedling stage and growth stage, while phosphorus and potassium fertilizer should be increased in the later stage of growth, that is, at the beginning of pelleting.
