What are the key points for planting asparagus? Appreciation of pictures attached

Asparagus is a kind of summer green leafy vegetable, which can not be eaten together with stems and leaves, but also can be separated as two delicacies. Hollow vegetables taste crisp, but the content of oxalic acid is relatively high, eating too much may affect the absorption of calcium. Now asparagus has been slowly on the market, the price is still relatively expensive, what are the key points for planting asparagus? Picture appreciation is attached.

1. Seed selection

On the whole, asparagus is generally planted from late April to early May every year. As the growth rate of asparagus is very fast, the branching ability is also very strong, so the demand for fertilizer and water is also more, so it is necessary to apply sufficient base fertilizer when applying fertilizer. When sowing, we should choose new seeds of the year that are relatively full and fresh in color, and the germination rate can reach more than 98%. The soil for planting asparagus should be loose and not hard. This kind of soil has good water absorption and dry seeds will germinate directly after sowing.

2. Land preparation

Before sowing, soil preparation should be carried out to make beds, and weeds in the field should be cleaned up in advance before land consolidation, so as to avoid the decrease of germination rate caused by weeds and seeds competing for nutrients after sowing. In order to prevent the occurrence of diseases and insect pests in hollow vegetables in advance, it is necessary to make preparations in advance in the daily management. When the asparagus enters the middle and later stage of growth, Zhuangcauling can be used to spray the surface. It can not only enhance the sturdiness of the rhizome and increase the yield, but also improve the disaster resistance of crops.

3. Base fertilizer

The application of basic fertilizer before sowing should be thorough to lay a good foundation for late sprouting. Generally speaking, the basic fertilizer is mainly organic fertilizer such as manure and soil fertilizer, and the amount of fertilizer per mu is about 600,800 kilograms. It should be noted that manure should be fully mature in advance before it can be used to avoid the occurrence of diseases and insect pests. Only the scientific application of fertilizer can promote the crop roots to be stout, and the leaves healthy and green to achieve the purpose of rapid growth, so as to significantly improve the quality and increase the yield.

4. Fertilizer and water management

Look at the dry and wet condition of the soil. If the soil is dry, it should be watered. When watering, the amount of water must be sufficient and should be drenched thoroughly. Let the soil fully absorb water. In the future daily management, generally speaking, watering can be carried out as long as the soil is relatively dry. Asparagus is a crop harvested many times, so in addition to applying sufficient base fertilizer, topdressing must be carried out in order to achieve high yield.

When the seedlings of asparagus grow to 5-10cm, they can be fertilized for the first time. Topdressing should be carried out according to the standard of 500-700kg organic fertilizer per 667m2. When topdressing, the fertilizer should be diluted first, and then fertilized with watering. Fertilize evenly. Otherwise, if there is too much fertilizer in a certain place, the plants will be burned. Generally speaking, it is OK to have a top dressing before harvest.
