Spinach fertilization method in winter (recommended collection)
Spinach is a nutritious vegetable that is popular among the masses. It is also a vegetable suitable for winter planting because it is very cold-tolerant, its seeds can germinate at a temperature of 4 °C, and it can be caught in a few degrees of weather, so it is very popular in winter. Then, if you want to grow spinach in the winter, how should you apply fertilizer? Is there a better fertilization method to make spinach grow better? Xiaobian has compiled some information here for reference. Let's first take a look at the fertilization points of spinach: When the spinach is grown in winter, the soil temperature is very low, which causes the soil digestion to weaken, while the spinach is sensitive to ammonium nitrogen fertilizer. Therefore, the ammonium nitrogen fertilizer can be used less at this time, and the appropriate use of nitrate nitrogen fertilizer. The top dressing of spinach can start in front of the bolting flowering, which can extend the flowering period of the spinach bolting. 1. Shiji fertilizer: Spinach grown in winter has a longer growth period, so the base fertilizer must be applied. Generally, organic fertilizer and phosphorus and potassium fertilizers are used as base fertilizers, and the whole layer of base fertilizer is applied, and then the soil is used as a base. 2. Reduce the application of nitrogen fertilizer before wintering: The cold resistance of spinach grown to 4-5 true leaves is the strongest, so it is best to keep 4-5 true leaves before the wintering of spinach, otherwise it will be more susceptible to freezing damage. If the sowing date is appropriate, and the base fertilizer is sufficient, the application of nitrogen fertilizer should be properly controlled before winter. If the planting is too late, consider applying nitrogen fertilizer to promote seedling growth. 3, after the return to green, timely dressing and watering: after the spinach returns to green, it is necessary to seize the opportunity of topdressing, topdressing can be carried out together with irrigation. The period of topdressing is generally applied twice in the middle and late March and the first half of April, because both the outside temperature and the soil temperature are rising. Fertilizer management has always been an important point in vegetable cultivation. Although the process is troublesome, but the production and quality of vegetables can be improved, I believe that everyone will feel that the previous hard work is very worthwhile.
