What fertilizer is the best for topdressing lettuce?

Lettuce has a crisp taste and can be eaten raw. It is easy to eat and rich in nutrition, suitable for both young and old. It is especially the main vegetable in domestic fast food restaurants of all sizes, so the planting prospect is very good and it is the main preferred variety for agricultural growers.

Anyone who has grown lettuce knows that lettuce seeds are small, but the leaves of the plant grow very fast after germination. Therefore, the row spacing should be larger when transplanting to provide sufficient space for the growth of lettuce. Otherwise, it will be too crowded and not conducive to growth, which will have a great impact on yield.

What fertilizer is good for topdressing lettuce?

Lettuce has a short harvest period and grows fast. Should we apply topdressing during these 40 days? I personally think that there is a big difference in yield between topdressing and not topdressing, and the taste will also be different. Therefore, it is recommended to apply topdressing during the growth period of lettuce .

First of all, before planting, you must choose a plot of land that is rich in organic matter and loose and breathable to ensure that the roots of the lettuce grow quickly.

If extremely acidic soil is chosen, its poor air permeability is not conducive to root growth. During management, it is easy to cause root growth difficulties, short and weak plants, and seriously reduce yields.

It is important to apply sufficient base fertilizer before planting. Choose decomposed pig, cattle and sheep manure, fermented manure and compost. These organic fertilizers are very rich in humus, and contain nitrogen, phosphorus, potassium, magnesium, zinc and other trace elements .

It not only makes the soil loose and breathable, but also retains water and fertilizer, but it is not easy to cause root burn. It has a long-lasting effect and provides sufficient nutrients for the lettuce throughout the growing period.

Topdressing of lettuce is mainly carried out on the fourth or fifth day after transplanting, when it has entered the normal growth stage. In order to promote faster root growth, urea, compound fertilizer or compost can be applied at the same time as watering. It is forbidden to apply fertilizer alone.

Watering must be done after each topdressing to prevent fertilizer from burning the roots. There should be an interval of about 10 days between each topdressing of fertilizer. When the lettuce grows to the point where it can be harvested, it is generally necessary to apply fertilizer 2 to 3 times .

When lettuce just enters the growth period, it is necessary to weed the field to prevent weeds from competing with vegetables for nutrients.

It is best to loosen the soil after the seedlings have grown, and then apply fertilizer 1 to 2 days later. This can ensure sufficient moisture in the soil, which plays an important role in promoting the rapid growth of lettuce .

When lettuce enters the growing period, it is very important to increase its yield and taste. Lettuce likes warm and moist soil. It is necessary to water and fertilize frequently to promote leaf growth and make the taste more crisp and tender.

When watering and applying fertilizer during the hot summer season, avoid high temperature periods, that is, field management work should be avoided between 10 and 16 o'clock.
