The planting time of the latest asparagus

Asparagus is a kind of vegetable originating in tropical rainy areas. it is grown in all parts of our country with rich nutrition and delicious taste. It is a common dish in the kitchen and has a high market prospect. Let's take a look at the planting time of asparagus.

Planting time of asparagus

Asparagus is usually planted from April to July every year and likes sufficient light, but it also has strong adaptability to close planting and loose requirements on soil conditions, but because it likes fertilizer and water, it is still better for the soil with relatively viscous weight and strong water and fertility conservation. Leaf tips grow a large number and rapidly, requiring large amount of fertilizer, strong fertilizer tolerance and high demand for nitrogen fertilizer.

The growth environment of asparagus

Hollow cabbage likes high temperature and humid environment, the seed germination needs more than 15 ℃, and the axillary bud of rattan must be kept above 30 ℃ at the initial stage of germination, so that the bud can sprout quickly and tidily, the suitable temperature for vine leaf growth is 25-30 ℃, the vine leaf grows vigorously, the picking interval is shorter, the high temperature is 35-40 ℃, and the vine leaf grows slowly below 15 ℃.

Planting techniques of asparagus

1. Soil preparation and fertilization: it is necessary to dig the soil deeply before sowing, apply 2500-3000 kg per mu of rotten organic fertilizer or 1500-2000 kg of human feces and urine, 50-2000 kg of plant ash, and rake flat and fine after mixing with the soil.

2, seed treatment: before sowing, the seeds are treated first, that is, soak the seeds in 50-60 ℃ warm water for 30 minutes, then soak the seeds in clean water for 20-24 hours, pick up and wash them and put them at a temperature of about 25 ℃ to accelerate germination. Rinse the seeds once a day with clean water and sow them once a day.

3. Sowing method: hollow cabbage generally adopts strip sowing and close planting, row spacing is 33 cm, and soil is covered after sowing. You can also use sowing or burrowing.

4. Field management: asparagus is a crop harvested many times, so in addition to applying sufficient base fertilizer, high yield can be achieved by topdressing many times. 10-15% rare manure and urine can be used at seedling stage, and the dosage is 1000-1500 kg per mu. When the seedlings have 3-4 true leaves, 15-20 kg of compound fertilizer and 2-4 kg of urea are mixed with 15-20 kg of compound fertilizer and 2-4 kg of urea. Asparagus needs a lot of water, so it should be watered frequently to keep the soil moist. During the growth period, there is no need for weeding and weeding during the growth period.

5. Timely harvest: hollow cabbage can be harvested 35-45 days after sowing. If it is an one-time harvest, it can be harvested at one time when the plant height is 20-35 cm. If it is harvested many times, the seedlings can be harvested at a time of 12-15 cm plant height, and the seedlings can be put on the market. When the plant height is 18-21 cm, the seedlings left behind can be harvested and listed for many times. When picking asparagus, it is more appropriate to pick it by hand.
