What techniques are there for planting asparagus? Please explain
For asparagus planting, you can refer to the following techniques:
Land preparation and fertilization. Choose a ventilated, sunny sandy loam soil with deep soil layers, a low groundwater table, a pH value of 6-6.7, and good air permeability, and the previous crop cannot be mulberry fields, orchards, rice, tomatoes, or similar plots. Deeply plow the land 30-40 cm, and in combination with plowing, apply 2000 kg of decomposed organic fertilizer per 1/15 hectare in concentrated furrows, then apply 30-40 cm planting furrows above the organic fertilizer, and per 1/15 hectare apply another 2000 kg of decomposed organic fertilizer in concentrated furrows, then above the organic fertilizer apply 30-40 kg of compound fertilizer or 20 kg of ammonium sulfate, mix the furrow soil evenly and rake it level, and irrigate thoroughly in preparation for planting.
Planting of nutrient pot seedlings in protected cultivation. The planting period is generally from early May to early to mid-June, and the soil preparation is the same as for direct-seeded open-field seedlings. When planting, follow the specifications of 1.2 m row spacing for green asparagus and 1.6 m for white asparagus, with a plant spacing of 30 cm, and plant in the planting furrows as the holes are dug. In order to make the growth direction of the new bud cluster emerging from the underground part consistent with the direction of the planting furrow, the first aboveground stem that sprouts must be placed along the furrow; the planting depth should be such that the seedling crown is slightly higher than the furrow surface, and after planting, water promptly and carry out shallow soil covering to a depth of 2-3 cm.
