How to make asparagus productive
Asparagus seeds form bulbs within two or three years after sowing. In spring, a lot of tender stems are extracted from the upper part of the bulb, which is usually eaten asparagus. Its long life, generally up to 14 years -18 years. After sowing and planting, the harvest can be harvested in the next year. The best asparagus hybrid generation can harvest 150kg-200kg/mu of fresh green asparagus in the second year. In the third and fourth years, the output of fresh bamboo shoots can reach 600-1000 kg/mu. Asparagus is suitable for crops cultivated in the cold winter and warm temperate climate in summer. In order to be able to adapt to the double requirements of breathable water retention, cultivation of asparagus in humus or sandy loam is ideal. Asparagus is more sensitive to the pH of the soil, and the soil pH (pH) is optimal between 5.8-6.7. During the dormant period, the underground part can tolerate a low temperature of -38 degrees Celsius, so its roots can safely pass through the frozen ground in a frozen layer of 1.5 meters. Asparagus seeds germinate the best temperature is 25 degrees Celsius -30 degrees Celsius, in the temperature changes within the harvested stems, most of the thick and thin bamboo shoots tight package, good shape and good quality. Asparagus underground meat root can store more water, but it can be adjusted by the amount of water in the soil. Asparagus metamorphose needle stems like needles, evaporation greatly reduced, so asparagus more drought-resistant. However, timely watering is a necessary condition for the high yield of asparagus. Asparagus is a kind of hi-light crop and requires sufficient sunlight for planting. Therefore, asparagus can grow on open land without shading. Source: "Peasant Daily" China Agriculture Network Editor
