Water spinach is very common in our life. Because its stem is empty, it is named and widely planted in the southern part of China. It is also a green leaf vegetable that we often eat in summer. With the increasing demand for water spinach, many farmers have planted spinach, so how can we make the spinach high-yield? What are the main points when applying fertilizer?

1, choose a variety

In general, spinach is generally grown from late April to early May each year. Since the growth speed of the water spinach is very fast and the branching ability is also very strong, the demand for the fertilizer water is also relatively large, so the base fertilizer should be applied when fertilizing. When planting, choose a new seed with a fuller, fresher color, and the germination rate can reach 98% or more. The soil in which the spinach is grown should be loose and not hard. The soil has good water absorption, and the dried seeds will germinate directly after sowing.

2, soil preparation

Before the sowing of the spinach, it is necessary to carry out the soil preparation and hoeing. Before we plant the land, we must clean the weeds in the ground in advance to avoid the weeding rate caused by the weeds and seeds competing for nutrients after sowing. In order to prevent the occurrence of pests and diseases in the spinach in advance, it is necessary to prepare in advance in daily management. When the spinach enters the middle and late growth stages, the stalk can be used to spray the surface. Not only can it strengthen the roots and strengthen the yield, but also improve the crop's ability to resist disasters.

3, base fertilizer

The application of the base fertilizer to the spinach before planting should be thorough, laying a good foundation for the later sprouting. In general, the basic fertilizer is mainly organic fertilizer such as manure and soil, and the amount of fertilizer per acre is about 600~800 kg. It should be noted that manure should be fully decomposed before use to avoid the occurrence of pests and diseases. Only the scientific application of fertilizer can promote the strong roots and stems of the crops, and the healthy green leaves of the leaves can achieve the purpose of rapid growth, thus improving the quality and increasing the yield.

4, top dressing

As a crop that has been harvested many times in the same year, the process of planting the water spinach is not only the application of the basic fertilizer, but also the multiple fertilization according to different growth stages throughout the growing season to achieve high yield. When the water spinach is in the seedlings, it can be drenched with 10%~15% of dilute manure, and the amount of fertilizer per acre is about 1000~1500 kg. The seedlings of the spinach grow 3~4 pieces of true leaves to be fertilized again. At this time, 15~20 kg of compound fertilizer and 2~4 kg of urea per acre should be used for fertilization. When the water spinach enters the picking period, the last top dressing is required after each harvesting, and 5-8 kg of compound fertilizer is applied per acre. When the spinach grows 5-10 cm seedlings again, the first additional fertilization can be carried out.

In the case of additional fertilization, it is necessary to apply 500-700 kg of organic fertilizer per acre of land as a topdressing standard. In addition, the fertilizer should be diluted in advance, and fertilization is carried out along with watering. It is necessary to pay attention to uniform application during fertilization to avoid the phenomenon that the fertilizer is burned to death in a place.

The above is the high-yield planting technology and fertilization points of the spinach, and there are many pests and diseases in the spring. Farmers should pay attention to prevent pests and diseases when planting the spinach. Farmers who want to grow water spinach must master the above planting points.
