3. In Changde, Hunan, ideal general-grade goods are sold at around 30 yuan, and singed-hair goods are sold at around 34 yuan.

III. How do you plant Davallia mariesii?

Davallia mariesii can be propagated by two methods, division propagation and rhizome propagation, but ordinary growers mainly use rhizome propagation. The planting methods for Davallia mariesii are introduced below:

1. Davallia mariesii prefers a cool and moist environment and likes fertile gravelly soil, so the planting site is suitable for understory areas with gravelly soil rich in humus. In addition, after complete reclamation, remove weeds and tree roots, break up the soil and rake it level, and apply thoroughly decomposed farmyard manure as base fertilizer. The planting site should have drainage ditches opened along contour lines to help conserve soil and water.

2. If the division method is chosen to propagate Davallia mariesii, it is suitable to do so in May-June. The specific method is to gently separate the mother plant, divide the creeping branches, plant 2-3 clumps per pot, and place them in half shade. When new leaves sprout on the rhizome, it indicates that the plant has survived. If rhizome propagation is used, select robust rhizomes with plump buds as seed material, cut them into sections and plant them in the field. Plant them shallowly and press firmly, then water.

3. After Davallia mariesii planting turns green and before the rows close, cultivate and weed 3-4 times each year. If the land where Davallia mariesii is planted has no shade, a shade shed also needs to be built, with a shade level of about 50%. In addition, during its growth period, liquid fertilizer can be applied as a top dressing, with a concentration not exceeding 1%, applied directly by broadcasting, at most once a week. Sufficient nitrogen will make the plant grow vigorously; insufficient nitrogen will make the old leaves of the plant turn gray-green and gradually yellow, with small leaves; excessive nitrogen easily makes the plant grow leggy and reduces resistance. Phosphorus is very important for root growth; a lack of it will make the plant short, with dark green leaves and underdeveloped roots. You can spray potassium dihydrogen phosphate, calcium superphosphate, and so on on the leaf surface to supplement phosphorus. Potassium can enhance photosynthesis and promote chlorophyll formation; if deficient, old leaves will develop spots and gradually wither and yellow.

4. Davallia mariesii often develops leaf spot disease in summer, with black-brown spots appearing on the leaves. It can be sprayed with 1:1:150 Bordeaux mixture or 50% carbendazim 1000-fold solution. Davallia mariesii can be dug throughout the year, generally mostly during the agricultural slack season or from April to August to dig the rhizomes.
