Asparagus is a perennial crop. At the end of winter and early spring, the ground plants are senescent and dormant, but are still dormant, but the underground roots continue to move and accumulate nutrients. It is necessary to seize this period to strengthen field management for high, stable and high-quality production in the coming year. Good foundation. The following is an introduction to safe wintering techniques for asparagus.

Clean up the bamboo garden. Asparagus shoots and shoots will wither during winter, and the stems and branches need to be removed by hand. Can not be removed when the aerial part is not completely withered, otherwise it will cause nutrient waste and affect the yield and quality of next year. The removal of dead branches should be carried out in the next few days when the weather is fine and sunny, and the water should not be watered immediately after being pulled out, otherwise it will easily cause wound infection, and It causes the underground part to rot. Root irrigation is applied to the stems and branches that have not withered to promote root development and strengthen root development. The dead branches brought out of the garden were burned.

Soil disinfection. After clearing the garden, a considerable amount of germs still remain in the soil. In order to make the invasion of the germs harm the plants, the occurrence of pests and diseases should be further controlled, and the soil should be disinfected after clearing the garden. Spray the tree with generals to disinfect the soil, and apply plant cell immune factors to improve plant resistance to stress, which can cause viral DNA to break and apoptosis. Strong immune function, induces interferon and active cytokines, inhibits residual virus replication, and promotes positive energy ecological growth of plants. Based on the mechanism of host plant disease resistance and the use of the principle of bacterial virulence mutation, control of plant physiological and invasive disease propagation.

Strengthen field management. Plant growth environment not only maintains moist moisture, but also sufficient nutrients to supply plant growth needs, it is necessary to topdress, topdressing and application of plant electronic fertilizer, a leader fertilizer that does not contain fertilizer elements, but can play an extraordinary role in fertilizer. Instead, it uses the principle of high-energy electrons and plant electronic polarity induction emanating from the photosynthesis of plants to improve cell division, molecular synthesis, and nutrient-matched digestion levels, accelerate the frequency of metabolism, and activate the plant nutritional grooming system to produce beyond fertilizer effects. Watering in time after topdressing is beneficial to the plant's absorption of fertilizer effect, and combined with cultivating, it can keep heat and protect the soil and prevent water evaporation.
