Planting skills of asparagus "King of vegetables" in Spring

Asparagus is the seedling of asparagus, a perennial herb of the genus asparagus in the asparagus family of the asparagus family. It is often eaten as a vegetable with high nutritional value. The ununearthed white asparagus is called white asparagus, and the unearthed asparagus is green. The following is to introduce the spring planting skills of asparagus, the king of vegetables.

First, timely raising seedlings

The common planting method of asparagus is sowing and raising seedlings, which can effectively improve the emergence rate of asparagus, enhance the quality of seedlings, advance the ripening time, and expand the utilization rate of land.

Use the method of sowing seedlings, when raising seedlings to choose rich and soft sandy soil, the soil layer does not need to be too thick, keep in the 20cm or so can, before sowing to apply sufficient base fertilizer, base fertilizer to mature poultry manure, phosphate fertilizer-based, because the temperature in spring has not completely rebounded, so after sowing to control the seedbed temperature to ensure that about 20 degrees, not less than 15 degrees, otherwise it may lead to frostbite and frostbite of the seedlings.

II. Soil preparation and fertilization

When raising seedlings, soil preparation should be carried out in the field. Asparagus is a perennial crop. Deep ploughing should be carried out before planting to ensure that the soil in the field is fertile and ventilated.

Soil PH value should not be too acidic or alkaline, and should be kept neutral, so it is necessary to neutralize asparagus when PH value is uncomfortable. Asparagus has very poor waterlogging tolerance, and it is also necessary to dig drainage ditches to facilitate later drainage work. Sufficient base fertilizer should be applied during soil preparation to improve soil fertility and promote the growth of asparagus seedlings.

III. Field management

After planting, the aim is to cultivate the root growth of asparagus. If asparagus is too thin, it is necessary to increase the nutrition ratio in time, do a good job of ploughing and weeding, fertilize properly according to soil fertility and asparagus growth, and pay attention to drainage after rain, otherwise it is easy to cause asparagus root retting.

September is a more important period in the growth of asparagus, the demand for nutrition will also increase greatly, so we should pay attention to replenish nutrients in time, water reasonably during harvest, keep the soil moist and prevent asparagus from drying and cracking due to lack of water.

IV. Pest control

Spring is also the season for the recovery of various germs and pests, so the incidence of asparagus in spring is very high. Disease and pest control in spring is an indispensable management work. While strengthening field management and doing a good job of water and fertilizer work, we should also disinfect the bamboo shoot garden regularly, understand the common diseases and insect pests of asparagus, and then carry out pest control work with purpose and direction, if the disease occurs. It is necessary to remove the diseased plant in time, and then check the cause and prescribe the right medicine.

The above is a brief introduction of asparagus planting skills in spring, asparagus disease resistance is relatively weak, so we should pay attention to do a series of management work in spring to avoid some unnecessary losses.
