How to plant day lily 1, and choose land for soil preparation.
Day lily has a strong ability to resist barren and drought, and does not need too much soil. However, in order to increase the yield of plants, it is best to choose a plot with deep soil layer, soft soil, flat terrain, shelter from the wind and sun, then dig deeply, apply sufficient decomposed organic fertilizer, and finally make a flat frame.
2. Reasonable close planting
Through reasonable close planting, the number of tillers, bolting and buds can be increased, thus achieving the purpose of increasing production. Generally, wide and narrow rows are used, with a width of 60-75cm and a narrow row of 30-45cm. The spacing between planting holes should be 9- 15cm, and 2-3 plants should be planted in each planting hole.
3, intertillage and soil cultivation
Because day lily is a fleshy root system, growing in a loose soil environment is more conducive to the development of roots. When planting, it needs to be cultivated in combination with soil hardening for 3-4 times, the first time 1 time is carried out at the time of emergence, and the second time-4 times is cultivated in combination with intertillage at the bolting stage.
4. Water and fertilizer management
After daylily is planted, high-quality farmyard manure and calcium superphosphate should be applied once, and then calcium superphosphate and potassium sulfate should be applied at the beginning of germination, and 0.2% potassium dihydrogen phosphate plus 0.4% urea and 2% calcium superphosphate should be sprayed on the leaves every 7 days during the picking period.
