Asparagus high yield first step: grasp the three steps of the spring tube
Regardless of whether white asparagus or green asparagus, it is very important to obtain the high yield and high efficiency of asparagus in the year, and it is very important to grasp the three steps of spring management. These three measures are: complete cleaning, rational fertilizer application, and scientific cultivation.
First, thoroughly clean the garden
Between the end of February and early March, the dried stems of the last year must be completely removed, including stems and stalks that are close to the ground, and should be pulled out by hand; the fallen leaves on the surface should be removed with a rake. Together with dead branches, they are transported to places away from the field. Because of the conidia and mycelium remaining in the above, if they continue to remain in the field, they will multiply in later growth periods, which will increase the occurrence of stem blight. According to our statistical survey, the field strain rate after the complete clearing of the garden was only 67%, and it was 685% without clear gardens.
After the clearing of the garden, the field must be ground-killed. Many farmers often neglect this point. Spraying 45% Schnelling on the ground 1500 times or 50% double Jisheng wins 400 times to disinfect the ground bacteria. Kill it.
Second, a reasonable fertilizer
Different growth stages, asparagus on the absorption and utilization of fertilizer is different, the spring asparagus on the fertilizer demand is 30% of the total, so blindly in the spring to increase fertilizer application, the effect of increasing production is not obvious.
Similar to white asparagus and green asparagus, master 50 kg of standard compound fertilizer in Mushi and 100 kg of organic compound fertilizer. Apply 30 cm away from the bamboo shoots plant. Open the ditch and apply 15 centimeters into the ditch. Do not get too close or too deep to avoid injury. To the root system.
If the land with less rain and snow last winter, the soil is relatively dry, and the spring water is poured once after top dressing, which can not only exert the fertilizer effect as quickly as possible, but also reduce the occurrence of hollow bamboo shoots.
Third, science cultivation
Green asparagus does not need to be ridged, but in combination with loose soil, it is appropriate to cover soil 15 centimeters for the bamboo shoots. This will not only increase the ground temperature, but also promote early-onset caving and yield increase, and also reduce the occurrence of weed damage.
The cultivation of white asparagus is carried out in the middle and middle of March. At this time, the ground temperature at a depth of 10 cm is about 10°C. The soil of the ridge should be dry and wet. If the soil is too dry, it should be watered several days in advance to open the ditch. After the fertilizer is applied, the soil is taken as a ridge, and the soil block is crushed and smashed to avoid bending later. The width of the ridge should be 60 to 80 cm, 25 to 30 cm high and 30 to 40 cm wide.
When cultivating ridges, there are sufficient conditions for labor, can be divided into 2 to 3 times training, so that through the sun can increase the ridge temperature, in order to facilitate the early high-yield. At present, most of the bamboo shoot area is formed by a ridge forming machine, which can save a lot of labor, but still need artificial ridges, ridges do not immediately, after 3 to 5 days, the effect is also very good.
Grasping the above management measures has laid the first step for the high output of the year.
(The next step is to describe the management requirements for the period of 4~8 months: scientific shooting and management)
