Asparagus Early Spring Management Technology

Due to the low price of asparagus in the past two years, most farmers have abandoned field management or made other crops in the asparagus fields. This has seriously affected the growth and yield of asparagus and caused premature death due to snow disaster in 2009, resulting in less accumulated nutrients. Scale and bud differentiation and reduction in the number of formation, if not take effective measures to strengthen the management of the spring, will result in serious reduction or no harvest. In order to increase the economic income of bamboo shooters, it is necessary to remind bamboo shooters that they must take effective measures to mitigate the impact of disasters, promote the development of bamboo shoots, and ensure that asparagus increases production and income.

First, strengthen the prevention and control of underground diseases and pests to promote root and scale bud development

According to tests, controlling the root rot disease of asparagus and the damage of the asparagus moth, the following medicines have been used to water the root plate. The effect is obvious: root disease clear (benzar bromamine + copper sulfate) 2000 times plus Lubaofeng (or Lubaofeng No. 1) ) 600-800 times more asparagus to protect the water agent 2000-2500 times plus chlorpyrifos 1000 times watering the root plate, each pier with liquid 100-150 ml.

Second, to strengthen fertilizer and water management to promote the development of bamboo shoots

Asparagus relaxes field management, premature stalks die, severe disease and insect pests, and early snow-damaged plant blocks. Roots and scale buds are heavily degraded or rot, and nutrient accumulation is less. It must be based on the development status of bamboo shoots and asparagus. Fertilizer requirements, take formula fertilization. Before the shoots germinate, per acre topdressing organic fertilizer 6,000 kg (or 100-150 kg of high-concentration amino acid organic fertilizer), 50 kg of amino acid asparagus fertilizer, asparagus Bao added powder 6-8 kg.

Third, according to the development of bamboo shoots, the correct harvest of asparagus

For spring and asparagus, where the buds are sparser and weak, they should adopt the method of first holding the mother's stem and then harvesting. Each of the piers should have 2-3 parent stems with a thickness of 1.2 cm or more and a thickness of 1.0 cm. Each of the piers has 4-5 stems selected and then harvested.

Special reminder: If the mother's stem is harvested from asparagus, we must strengthen the management of the field to ensure the normal healthy growth and development of the stem, to avoid artificial, mechanical damage, pest damage and wind blow.
