Crop intercropping
. The aboveground part of day lily is not cold-resistant, and the underground part is cold-resistant to-10℃. Avoid excessive soil moisture or water accumulation. When the ten-day average temperature is above 5℃, seedlings begin to emerge, and the suitable temperature for leaf growth is 15℃ ~ 20℃. Flowering requires high temperature, and 20℃ ~ 25℃ is more suitable. Daylily planted in dry land is not as thick as paddy field and tastes better.
First of all, day lily
Day lily, also known as day lily.

Liliales
Liliaceae
perennial herb
The roots are nearly fleshy, and the middle and lower parts are often spindle-shaped. Scapes vary in length, pedicels are short, flowers are numerous, and perianth is yellowish.
tangerine
Black and purple; Capsule obtuse triangular oval, flowering and fruiting from May to September.
Day lily is sweet and cool, and has the effects of stopping bleeding, diminishing inflammation, clearing away heat, promoting diuresis, promoting digestion, improving eyesight and calming the nerves.

Can be used as a tonic after illness or postpartum.
Second, the cultivation method
1、
rational close planting
. Using close planting can give full play to group advantages and increase tillering.
bolt
Achieve the purpose of increasing output.
2. Appropriate deep planting. The root group of day lily comes from
Dwarf stem
Growing around, 1 year, 1 layer, the rooting position moves up year by year from bottom to top, so proper deep planting is beneficial to the survival and prosperity of plants, and the suitable planting depth is 10~
15cm
3. Intertillage and soil cultivation. Day lily is a fleshy root system and needs to be fertile and loose.
soil environment
Conditions can be conducive to the growth and development of root groups, and the growth period should be based on growth and
Soil hardening
Situation: intertillage for 3~4 times, 1 time when the seedlings are just unearthed, and cultivate the soil at bolting stage for 2~4 times.
4. Fertilize. Day lily needs all-winter fertilizer (base fertilizer), early seedling fertilizer, heavy fertilizer and topdressing.

Fat.
Winter fertilizer (base fertilizer). The growth of the aboveground parts of the day lily should stop, that is, the autumn seedlings frost.

After planting or during planting, organic fertilizer is the main material, and high-quality farmyard manure is 30,000 kg/
hektare
、
calcium superphosphate
750 kg/ha.
Seedling fertilizer. Seedling fertilizer is mainly used for seedling emergence and leaf growth to promote the early growth and rapid development of leaves; Seedling fertilizer should be applied sooner rather than later, topdressing should be applied when the day lily begins to germinate, topdressing calcium superphosphate 150kg/hm2,
potassium sulfate
75 kg/ha.
Fat. The bolting period of day lily is from
Vegetation growth
be transformed into
reproductive growth
Important period, this period needs more fertilizer, it should be in
card
Pumping started topdressing, urea was 225kg/hm2, calcium superphosphate 150kg/hm2 and potassium sulfate was 75kg/hm2.
Ferrer. Bud fertilizer can prevent premature senescence of day lily, improve bud formation rate, prolong harvest period and increase yield; 75kg/hm2 urea should be topdressing 7~ 10 days after picking. At the same time, spray 0.2% on the leaves every 7 days during the picking period.
Monopotassium phosphate
, add 0.4% urea, add 1%~2% calcium superphosphate (filtered) aqueous solution, and add 15~20mg/kg jiu2o in 17:
the post-00s generation
Spraying 1 time has obvious effects of strengthening buds and preventing buds from falling off.
