Latest Asparagus High-Yield Pollution-Free Planting Technology and Method Tutorial
Asparagus is a vegetable with very high nutritional value in China, and it has a very wide planting area in China. Now the people of China have increasingly higher demands for vegetables, so new pollution-free high-yield planting technologies for asparagus have gradually emerged. While ensuring yield, it can also prevent excessive pesticide residues. So how exactly should we do it? Below, the editor brings you the high-yield pollution-free planting technology for asparagus. Let's take a look!
1. Seed selection and site selection
Variety has a very high relationship with asparagus yield, so before planting asparagus we must do a good job of selecting asparagus varieties. We should choose reasonably from various aspects such as production performance, quality and stress resistance. Then we need to do a good job of site selection. Pollution-free planting can mainly be understory planting, so we had best choose poplar forests, pay attention to pest and disease conditions, and control the plant and row spacing at about 5 m. The terrain must not be low-lying, ensure convenient transportation, and finally ensure that the soil fertility is high, permeability is strong and drainage and irrigation are normal.
2. Land preparation and trench digging
Before asparagus is planted, we must do a good job of land preparation, level the soil, and then deep plow about 35 cm. Repeatedly plough the soil to ensure the soil is sufficiently loose, the ground is clean and permeability is good, so as to ensure normal growth of asparagus, and then apply an appropriate amount of base fertilizer according to the planting area. Then control the planting density of asparagus well and dig the planting trenches. When planting in poplar forests, the asparagus planting area can reach about half. The depth of the planting trench should be kept at 35 cm, depending on the soil quality.
3. Timely planting
Around Qingming Festival every year should be the best time for transplanting and planting asparagus. Because at this time the scale bud disc of asparagus has not yet fully sprouted, the root capacity of asparagus 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 above the stem. Then plant the asparagus and begin filling soil on both sides. This can promote asparagus to develop in a horizontal direction and effectively increase yield.
4. Strengthen management
To plant asparagus, first of all we need to do a good job of water and fertilizer management. We should reasonably adjust fertilization time and fertilization amount according to the growth of asparagus young 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 the actual situation. In areas with little water, water about once every 10 or so. Finally, we need to do a good job of various management tasks such as intertillage and weeding, pest and disease control. Only by strengthening management can we ensure better growth of asparagus and increase yield.
The above is a brief introduction to the high-yield pollution-free planting technology for asparagus. 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.
