Xiaodu, Xiaodu: My spinach is growing too slowly now, what fertilizer can I use to improve its growt

What fertilizer is used for spinach to grow slowly?

First of all, we need to know what nutrients are needed for plant growth, and the three major elements that plants need are nitrogen, phosphorus and potassium, and the symbols are n p k!

Nitrogen fertilizer is mainly long-leafed, and the dark green nitrogen fertilizer on the leaves is sufficient, and the general urea is nitrogen fertilizer!

Phosphate fertilizer is mainly to promote the differentiation of flower buds, more branches, more germination, more flowering, general superphosphate, animal dry manure is to supplement this!

Potassium fertilizer is to promote rhizomes, fruit expansion, peel coloring, flowers are gorgeous, chemical fertilizer is potassium dihydrogen phosphate, organic fertilizer is animal dry manure!

Spinach grows too slowly, so you can apply human urine every 10 days. Combine a single spray of brassinin plus potassium dihydrogen phosphate.

The temperature is low, and it doesn't work in fertilizer.

Summary. Spinach likes to grow in alkaline soil, and has high requirements for nitrogen, phosphorus and potassium fertilizers, especially potassium fertilizers, which are conducive to improving the yield and quality of spinach, and potassium deficiency can easily lead to yellowing of leaves, resulting in unripe spinach sprouts.

Second, spinach fertilization technology.

1. Fertilize before wintering.

Generally speaking, spinach that kind of strict fertilization management, can achieve high yield, if the winter spinach seedlings are strong, you need to apply 3000kg of rotting organic fertilizer, when the spinach seedlings grow to 2-4 leaves, apply an appropriate amount of nitrogen fertilizer, to promote the seedlings to be robust.

Summary. In the soil lacking in trace elements such as iron, zinc, manganese, boron, etc., it is easy to have yellow leaves, small leaves, soft rot, etc., and the trace element solution can be sprayed 2 or 3 times during the growth period to improve the stress resistance of spinach and promote the growth of spinach.

Hello,Xiaodu is thinking about it seriously.,You wait for me.。

Spring spinach is sown early, and it can be fertilized before the Spring Festival, and rotting organic fertilizer can be applied.

It is advisable to choose neutral clay soil for summer spinach, and a mixture of soil miscellaneous fertilizer and chemical fertilizer can be used as base fertilizer.

Spinach can be sprinkled with fast-acting nitrogen fertilizer appropriately.

or high-nitrogen compound fertilizer to promote thicker leaf growth, increase yield and improve quality.

Precautions: The growth period of spinach is short, and it is best to use fast-acting fertilizer for base fertilizer and top dressing. Careful application of ammonium nitrogen, spinach is more sensitive to ammonium ammonia, the production season of overwintering spinach is at the junction of autumn and winter and spring of cherry blossoms, the soil temperature is low, the nitrification of the soil is very weak, and the ammonium nitrogen fertilizer will not be converted into nitrate nitrogen soon after application, so it is best to use nitrate nitrogen fertilizer.

In the soil lacking in trace elements such as iron, zinc, manganese, boron, etc., it is easy to have yellow leaves, small leaves, soft rot, etc., and the chiral trace element solution can be sprayed 2 or 3 times during the growth period to improve the stress resistance of spinach and promote the growth of spinach green feet silver.
