Detailed Explanation of High-Yield and Pollution-Free Asparagus Cultivation Techniques
Asparagus is a vegetable with very high nutritional value in China, and it is grown across a very wide area in the country. Nowadays, Chinese people have increasingly high demands for vegetables, so new pollution-free, high-yield cultivation techniques for asparagus have gradually emerged. While ensuring yield, these techniques can also prevent pesticide levels from exceeding standards. So how exactly should we go about it? Below, the editor brings you the high-yield and pollution-free asparagus cultivation techniques. Let's take a look!
1. Variety and Site Selection
Variety has a very strong influence on asparagus yield, so before planting asparagus we must do a good job of selecting the asparagus variety. We should choose rationally based on production performance, quality, stress resistance and other aspects. Then we need to do a good job of site selection. Pollution-free cultivation can mainly be done under forest stands, so we had best choose poplar groves, paying attention to pest and disease conditions, with plant and row spacing controlled at about 5 m. The terrain must not be low-lying, and convenient transportation must be ensured. Finally, make sure the soil has high fertility, strong permeability, and normal drainage and irrigation.
2. Land Preparation and Trench Digging
Before asparagus is planted, land preparation must be done well. Level the soil, then deep-plow to about 35 cm. Plow the soil repeatedly to ensure it is sufficiently loose, the ground is clean, and permeability is good, so as to ensure normal asparagus growth, then apply an appropriate amount of base fertilizer according to the planting area. Then control the planting density of asparagus and dig the planting trenches well. When planting in poplar groves, the asparagus planting area can reach about half. Keep the depth of the planting trenches at 35 cm, depending on soil quality.
3. Timely Planting
Around Qingming Festival each year should be the best time to transplant and establish asparagus. This is because at this time the asparagus bud scale disc has not yet fully sprouted, the asparagus root capacity is relatively poor, and new roots have not yet fully developed. Therefore, if seedlings are lifted and transplanted at this time, the survival rate is high and the yield also increases very noticeably. When planting asparagus, the depth should be controlled at about 9 cm of the stem. Then establish the asparagus and begin filling soil on both sides. This can encourage asparagus to develop horizontally and effectively increase yield.
4. Strengthen Management
To grow asparagus, first of all, water and fertilizer management must be done well. We should rationally adjust fertilization timing and amount according to the growth of young asparagus stems. At about 10 cm, begin the first water and fertilizer application, dig a fertilization trench at a position about 20 cm from the plant, and apply fertilizer in the trench and cover with soil. Then do a good job of watering according to actual conditions; in areas with little water, water about once every 10 or so. Finally, do a good job of various management tasks such as intertillage and weeding, and pest and disease control. Only by strengthening management can we ensure better asparagus growth and increase yield.
The above is a brief introduction to high-yield and pollution-free asparagus cultivation techniques. Asparagus is very popular, but while increasing yield, we also need to pay attention to ensuring quality, so everyone must pay close attention. That is all for today's introduction.
