When should we apply fruit-enlarging fertilizer to water chestnuts? What fertilizer is good for water chestnuts during their enlargement period?

Water chestnut is a household-known plant. It can be eaten not only as a fruit but also as a vegetable. In the past two years, the price of water chestnut has risen and is higher than that of many fruits. So how can water chestnut be fertilized to achieve high yield?

When to apply fruit-enlarging fertilizer to horseshoe

During the expansion period of Calla lily, nitrogen fertilizer and water-soluble fertilizer can be used to apply fruit-swelling fertilizer. During the expansion period of Calla lily, apply fertilizer once every 7 days . The amount of fertilizer applied each time should be controlled at about 40kg per mu. After that, apply appropriate topdressing according to the growth of the plant.

During the fruit-bearing period of water chestnut, fertilizer should be applied according to the growth of the plant. During the fruit-swelling period, the use of nitrogen fertilizer should be controlled, generally about 120 kg per mu.

What fertilizer is good for horseshoe in the later stage

In the later stage of planting, it is better to apply urea, nitrogen, phosphorus and potassium compound fertilizers to water chestnuts. In the early stage, farmyard manure is used as base fertilizer, and urea solution and nitrogen, phosphorus and potassium compound fertilizers are applied once in the later stage. When applying fertilizer, the concentration must be diluted before use to avoid fertilizer damage.

Sowing as early as possible can effectively increase the yield. The planting time is generally around July-August, and no later than October. During the planting period, sufficient water, high temperature and sufficient light should be ensured.

How to fertilize horseshoe for the best effect

Water chestnuts have strong tolerance to fertilizers, so they require sufficient organic fertilizers and compound fertilizers. The principle is to " apply a lot of base fertilizer, apply topdressing in a clever way, and apply micro-fertilizers ." Note that the fertilizer should not be too concentrated; for late-season water chestnuts, apply a little more topdressing, mainly quick-acting fertilizers.

1. In the early growth stage when the mother plant cluster begins to form, the nitrogen content in the plant is relatively high. The nitrogen content is lowest when the pod-bearing runners emerge, and a large amount of nitrogen is required when tillers and leaf-like stems grow.

2. The peak period of phosphorus content is during the tillering and division period, and then gradually decreases. Phosphorus should be applied as basal fertilizer.

3. The content of potassium in the plant body is much higher than that of nitrogen and phosphorus. The peak period of potassium fertilizer absorption is during the division and pod setting stage. In addition to potassium as base fertilizer, special potassium fertilizer should be applied in the middle and late stages.
