The latest planting techniques of asparagus in spring

Asparagus is a kind of vegetable with high nutritional value, which ranks high among the vegetables in our country. Now after entering the winter, the management of asparagus is also onerous. Many friends have done the work of overwintering to facilitate asparagus in the following spring. However, it is inevitable that asparagus will not adapt to the changing season in winter and spring. Therefore, it is necessary to change the planting method appropriately, so the editor brings you the planting skills of asparagus in spring today. Let's have a look!

1. Timely raising seedlings

The common planting method of asparagus is sowing and raising seedlings, which can effectively improve the emergence of asparagus, enhance the quality of seedlings, advance the ripening time, and expand the utilization rate of land. When raising seedlings, we should choose rich and soft sandy soil, the soil layer does not need to be too thick, it can be kept at about 20 centimeters. Before sowing, we should apply sufficient base fertilizer, which is mainly based on rotten poultry manure and phosphate fertilizer. And the temperature in spring has not completely rebounded, so it is necessary to control the seedbed temperature after sowing to ensure that it is about 20 degrees, not less than 15 degrees.

2. Soil preparation and fertilization

When raising seedlings, soil preparation should be carried out in the planting field. Asparagus is a perennial crop and should be ploughed deeply before planting. The soil PH value should not be too acidic or alkaline, but should be kept neutral, so neutralization should be done when the PH value is not suitable. To ensure that the field soil is fertile enough, ventilation and permeability is strong, the waterlogging resistance of asparagus is very poor, so it is necessary to dig a good ditch to facilitate the later drainage work. Then apply sufficient base fertilizer during soil preparation to improve soil fertility and promote the growth of asparagus seedlings.

3. Field management

After planting, the purpose is to cultivate the root growth of asparagus. If the asparagus is too thin, then it is necessary to increase the nutrition ratio in time and do a good job of weeding in the middle tillage. Then according to the soil fertility and asparagus growth and other appropriate topdressing, after the rain should pay attention to drainage, otherwise it is very easy to cause asparagus root retting. Around September is an important period in the growth of asparagus, and the demand for nutrition will increase greatly. Therefore, it is necessary to replenish nutrients in time, and water reasonably during harvest to keep the soil moist and prevent asparagus from drying and cracking due to lack of water.

4. Pest control

Spring is also the season for the recovery of various germs and pests, so the incidence of asparagus in winter is very high. Therefore, our disease and pest control in spring is also an indispensable management work, strengthen field management, do a good job of water and fertilizer work at the same time. It is also necessary to 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, the diseased plant should be removed in time, and then check the cause and prescribe the right medicine to the case.

The above is a brief introduction of asparagus planting skills in spring, asparagus disease resistance is relatively weak, so we must do a good job in these management work to avoid some unnecessary losses. That's all for today's introduction. This article is for reference only. I hope it can help you all.
