Occurrence and control of common diseases of asparagus
Asparagus blight 1. Symptoms. Asparagus vertical blight, also known as Fusarium wilt, is a soil-borne disease. For the first time, individual plants in the field turned yellow and wilted, the whole plant withered after the disease spread, the tender stem was infected, the leaves and stems turned brown or split longitudinally, the underground stem and root of the diseased plant showed brown disease spot, and the diseased part rotted in the later stage, producing white to pink.

Asparagus sowing and management after sowing
First, sowing time is to make use of the longest growing season, sowing as early as possible in spring. The sowing time should be 18 ℃ 20 min after the frost period. The higher the ground temperature, even up to 32 ℃, the faster the sprouting. Sowing too late in the growing season can lead to smaller mother plants. So if you sow too late in the growing season, do your best.

Comprehensive prevention and control of asparagus diseases and insect pests
In the prevention and control of diseases and insect pests, scientific control measures should be adopted, pollution-free control technology should be vigorously promoted, and pesticides with high toxicity and high residues should be banned, so as to not only effectively control the harm of diseases and insect pests, but also make the pesticide residues in the products do not exceed the standard. In the prevention and control, take "prevention first, comprehensive prevention and control" measures, timely early prevention. (1) Agriculture.

What to do about sweet potato growing after rain?
The early or late of deep ploughing and soil improvement, the speed and duration of tuber expansion are all directly related to the ventilation of the soil. If the soil ventilation is poor, the lack of oxygen will hinder the root root respiration and nutrient absorption, thus inhibiting the root expansion. Therefore, if you want sweet potatoes.

Occurrence and control of stem rot of asparagus
1. Symptom characteristics asparagus stem rot mainly harms young bamboo shoots. The young bamboo shoots may be damaged after they are unearthed, and the young stems appear water-like amorphous disease spots, which expand around the stem, resulting in stem tissue disintegration and decay, resulting in the death of young bamboo shoots. If the disease is light, even if it does not wither and die, its growth potential is greatly reduced, the aboveground stems and leaves are weak, the young stems are weak, and the yield.

Cultivation techniques of asparagus intercropping with vegetables
Asparagus brown spot is an important disease affecting the quality and yield of asparagus, which is common in many places. 1. Pathogen: asparagus brown spot is a disease caused by the infection of fungus subphyllosporium. 2, symptom identification: plant disease, stem, lateral branches and pseudo-leaves will be damaged; diseased leaves yellowing, withering, shedding.

High-yield cultivation and management techniques of asparagus
Asparagus is one of the highly efficient cash crops, which can be harvested for more than 10 years at one time. The annual harvest of bamboo shoots per mu is generally 2300 kg, and the output value per mu is more than 10,000 yuan. Fresh bamboo shoots are rich in protein, cellulose and a variety of trace elements, which have the effects of promoting blood circulation, promoting menstruation and preventing cancer. Its high-yield cultivation and management techniques should be grasped as follows.

High yield technology of asparagus
Asparagus seeds form bulb disks within two or three years after sowing. In spring, many tender stems are extracted from the upper part of the bulb disk, which is usually eaten asparagus. Its life span is long, generally up to 14-18 years. After sowing and planting, it can be harvested in the second year. Excellent asparagus hybrid species can harvest 150 kg-2 fresh green asparagus in the second year.

Main cultivation techniques of asparagus
1. Yang border should be selected to raise seedlings in the leeward to the sun, easy to irrigate and close to the bamboo shoot field. Generally, the border is east-west, with a length of 10 mi 13 m, a width of 1 mi 1.5 m, a depth of 20 mi 25 cm, and a rammed wall with a thickness of 25 cm, high in the north and low in the south.

Management techniques of asparagus in summer and autumn
Asparagus is one of the highly efficient cash crops, which can be harvested for more than 10 years at one time. The annual harvest of bamboo shoots per mu is generally 2300 kg, and the output value per mu is up to 10,000 yuan. The key to its high-yield cultivation and management is as follows: first, to cultivate strong seedlings to capture the high yield of asparagus, in addition to selecting good varieties, it is also necessary to establish a nursery.

Anti-season cultivation techniques of asparagus in greenhouse
The hybrid varieties with strong disease resistance and fast growth were selected, such as 2000-3 and Champion. The main way of sowing and raising seedlings is from February to April. Soak the seeds with 50% carbendazim wettable powder for 12 hours, then soak them in 30-35 ℃ warm water for 2-3 days, remove the seeds, cover them with wet towels and rinse the seeds with warm water every day.

Causes and control of a large number of dead plants of asparagus
The reasons for asparagus death are as follows: 1. Asparagus likes light. From September to October 2007, when the aboveground parts of asparagus grew vigorously and accumulated nutrients, laying the foundation for the next year's high yield, we suddenly encountered the continuous overcast and rainy weather that we had not seen for many years, resulting in a serious lack of light, resulting in stagnation of asparagus growth, decrease of nutrition accumulation and stress resistance.

Key points of asparagus seedling raising technique
The main points of cultivation techniques of asparagus are introduced as follows: first, the selection of varieties is different from other vegetables. Asparagus is a perennial plant, and it can be harvested continuously for 15 years at one time. Therefore, the first generation hybrid varieties with disease and insect resistance, strong stress resistance, short dormancy period, good commodity, high quality and high yield should be selected. Second, education.

Breeding and propagation methods of asparagus
1. Select good seeds: asparagus generally propagates with seeds, so it is very important to select good seeds. Asparagus seeds can be preserved for 3-5 years under good storage, but in production, the actual effective life is 2-3 years. If there is no sealed packaging, and stored in a humid environment, the germination rate of seeds will soon be lost. Let the seed.
