Ecological planting method of interplanting Ophiopogonjaponicus with corn and
garlic
The invention relates to the technical field of Ophiopogon japonicus planting, in
particular to an ecological planting method of Interplanting Ophiopogonjaponicus with
corn and garlic.
Ophiopogon japonicus is a perennial herb, which is used as an important Chinese
medicinal material with dry root tubers. Its medication has a long history and remarkable
curative effect. It has the effect of nourishing yin and promoting body fluid, moistening
lung and clearing heart. It is commonly used in dry cough of lung, tuberculosis cough of
yin deficiency, sore throat, thirst caused by body fluid injury, heat and thirst elimination,
insomnia, constipation caused by intestinal dryness and other diseases. Clinically, there are
more than 530 traditional Chinese medicine prescriptions containing Ophiopogon
japonicus. There are more than 194 health food containing Ophiopogon raw materials, and
the market prospect is very good.
Wild Ophiopogon japonicus mostly grows in hillside, undergrowth, forest edge or
barren grass with good biodiversity. Moreover, Ophiopogon japonicus likes shade and
strong illumination, which is not conducive to the accumulation of photosynthetic products
and the increase of medicinal material yield. Although artificial cultivation can ensure the
production of medicinal materials. At present, Ophiopogonjaponicusis mostly cultivated
in the open field, and there are serious problems of autotoxicity and continuous cropping
obstacles in planting, which are often manifested as soil hardening, acidification, increase of nematodes and aggravation of soil-borne fungal diseases. Moreover, in the case of long term monoculture, the yield of Ophiopogonjaponicusis fixed, the land resources are fixed, and the economic value is limited.
Ecological planting is an effective way to solve the above problems. In ecological
planting technology, the most commonly used means and method is ecological planting
based on species diversity. Rational allocation of different exogenous biological
populations through diversity cultivation technology and the principle of living things can
improve the habitat, restore the ecological function of soil and increase the yield. As a new
mode of Chinese herbal medicine production, ecological planting based on species
diversity can not only effectively control the soil pollution and continuous cropping
obstacles of Chinese herbal medicine cultivation, but also protect the site conditions and
soil micro-ecology of Chinese herbal medicine agriculture, and ensure the yield and quality
of Chinese herbal medicine.
Ophiopogonjaponicusplants are short, and wild Ophiopogonjaponicusgrows under
forests. Therefore, the cultivation of Ophiopogon japonicus should meet its shade
conditions according to its biological characteristics. Intercropping other crops, such as
corn, is a better choice. Ophiopogonjaponicus is in the seedling stage in April, which is
not suitable for strong light, and corn can shade it; In addition, reasonable interplanting of
garlic will precipitate allicin and other chemicals in Ophiopogonjaponicusfield. Garlicin
has a strong bactericidal effect on microorganisms and pests in soil, and can effectively
prevent and reduce the occurrence of pests and diseases.
In view of this, it is necessary to change the planting mode of Ophiopogonjaponicus
and invent an ecological planting method of interplanting Ophiopogonjaponicuswith corn
and garlic, so as to solve the above problems.
To solve the above problems, this paper provides an ecological planting method of
interplanting Ophiopogonjaponicuswith corn and garlic. This method makes full use of
the land resources and three-dimensional space of Ophiopogonjaponicus, realizes shade
of Ophiopogonjaponicus, and reduces the occurrence of diseases and insect pests. It not
only promotes the growth and yield of Ophiopogon japonicus, but also improves the
utilization rate of light energy, space and land, and inhibits the growth of weeds. Th e
method effectively reduces the application amount of pesticides and fertilizers, protects the
ecological environment of farmland, and realizes the triple harvests of medicine, grain and
vegetables.
Specifically, an ecological planting method for interplanting Ophiopogon japonicus
with corn and garlic comprises the following steps:
SI. Land selection and preparation: selecting sandy soil land with fertile, loose and
humid soil and flat terrain; Land preparation is carried out before and after Tomb-Sweeping
Day, the depth of cultivated land is 20 ~ 30 cm, and sufficient base fertilizer is applied at
the same time, and the base fertilizer is mixed with fully decomposed farm manure and
decomposed oil cake;
S2. Raising seedlings of Ophiopogon japonicus: selecting upright Ophiopogon
japonicus with dark green and strong color or creeping Ophiopogonjaponicus with wide and short leaves as seedlings, cutting off the lower rhizomes and fibrous roots of the selected seedlings, and keeping the upper tendril part and the stem nodes below lcm;
S3. Planting and watering root fixing water: planting from April 5 to April 20 every
year with a planting depth of 3-4 cm; Irrigation of root fixing water immediately after
planting;
S4. Intercropping corn: after planting Ophiopogonjaponicus,furrowing is carried out
in the Ophiopogon japonicus planting field, while every 7-13 rows of Ophiopogon
japonicus are furrowed, zinc fertilizer is applied as a base fertilizer at the bottom of the
furrow, the zinc fertilizer is 1.Okg/667m 2, and corn seeds are sown on the ground after
being covered with shallow soil;
S5. 10-15 days before corn harvest, planting garlic petals into the planting field of
Ophiopogonjaponicus.
Preferably, in step Si, when applying base fertilizer, 30005000Kg of fully
decomposed farm manure and 50-100 kg of decomposed oil cake are mixed and applied
every 667m 2 .
Further, in step S3, when planting, a special nesting machine for Ophiopogon
japonicus is used to nest and then plant, or ditch or pry the nest; The plant spacing is
1Ocmxcm, or the ditch spacing is 12-13 cm, and the plant spacing is 8 -9 cm.
Optimally, in step S4, the planting density of corn is 3000-4000 plants /667m 2, the
spacing between plants is 20-26 cm, and multiple seeds are sown in a single row.
Furthermore, the interplanting corn adopts a corn variety with compact plant type in
middle stalk and middle spike.
Further, in step S5, when garlic is planted, firstly, the garlic petals are sterilized, and
then planted in the Ophiopogonjaponicusplanting field with a row spacing of 40-50 cm
and a spacing of 10-15 cm, while the plant form is burrow digging.
In addition, the method includes stubble selection: the corp planted initially can be
vetch, rice, rice field, garlic, wheat, rape or non-root Chinese medicine.
Field management is also included: irrigation must be done in time during the growth
period of Ophiopogon japonicus to keep the soil moist; Shallow cultivation should be
carried out in July-August and September-October. The depth of cultivation should be less
than 3 cm without damaging roots and plants. After planting Ophiopogon japonicus
seedlings, weeding should be done once every 15 days. From May to December, weeding
should be done once or twice a month to keep the planting field clean.
After the emergence of corn, thinning seedlings or replanting seedlings are carried out
according to the growth trend; In the late stage of corn wax ripening, the top and foot leaves
are removed in time, that is, the upper straw at 3 ~ 4 leaves on the ear of corn is cut off,
and the foot leaves below the ear are removed, and Ophiopogonjaponicusis exposed. After
the corn matures, it is harvested in time and the corn straw is cut off.
The invention has the beneficial effects that the yield of Ophiopogon japonicus is
increased, and the economic benefit is increased.

In order to have a clearer understanding of the technical features, objectives and
effects of the present invention, specific embodiments of the present invention will now be
described with reference to the drawings.
As shown in Fig. 1, an ecological planting method of interplanting Ophiopogon
japonicus with corn and garlic comprises the following steps:
(1) Selection of stubble: crops such as vetch, rice, seedling field, garlic, wheat and
rape or non-root Chinese medicinal materials should be selected for the previous crop, but
crops such as tobacco and milk vetch or other root medicinal materials should not be
selected.
(2) Land selection: Choose sandy soil with convenient irrigation water, fertile, loose
and humid soil and flat terrain.
(3) Land preparation: prepare land before and after Tomb Sweeping Day, with the
depth of cultivated land being 20 ~ 30cm, plough the soil, hoe weeds, stones and roots of
previous crops in the field, and rake and level them. Combined with land preparation,
3000-5000Kg of fully decomposed farmyard manure and 50 ~ 100 kg of decomposed oil
cake are applied as base fertilizer every 667m 2 , which are mixed, thinned and raked.
(4) Seedling raising of Ophiopogon japonicus: When harvesting Ophiopogon
japonicus, plants of erect Ophiopogon japonicus with dark green and strong color or
creeping Ophiopogonjaponicuswith wide short leaves are selected as seedlings. Cut off the lower rhizomes and fibrous roots of the selected seedlings, keep the upper tendrils, and keep the stem nodes less than lcm. It is better that the leaves do not scatter and the cross section of the rhizomes presents white radial pattern. If the remaining rhizomes are too short, it will affect the germination of new roots and even prevent them from rooting; If the remaining rhizomes are too long, the growth of tubers will be affected and the yield will be reduced. For seedlings that cannot be planted in time, it is necessary to raise seedlings, put the seedlings on loose soil in damp places, and protect the seedlings with fine soil around the base of the stem, so that the roots of the seedlings are buried in damp soil.
Seedling raising time should not be too long, generally no more than 7 days, and the soil
must be kept moist during seedling raising.
(5) Transplanting Ophiopogon japonicus: Transplanting Ophiopogon japonicus
seedlings on cloudy days from April 5 to April 20 every year, no later than the end of April.
The planting density of Ophiopogonjaponicusper 667m 2 is 60,000 ~ 70,000 plants,
which can be planted after nesting with a special nesting machine of Ophiopogon
japonicus. The plant spacing is 1OcmxOcm, or the ditch spacing is 12 ~ 13 cm, the plant
spacing is 8 ~ 9 cm, and the planting depth is 3 ~ 4 cm. Ophiopogonjaponicusplanted in
the first half of April has the advantages of easy survival, quick rooting, early formation of
Ophiopogonjaponicus,good quality and high yield per unit area. Therefore, if the planting
time can be advanced properly, the investment can be reduced and the yield can be
increased, which is an economic measure to increase production.
(6) Irrigation of root fixing water: Irrigation should be done immediately after
planting, and the height of flooded seedlings should be about 5cm. After planting drought,
water should be timely to keep the soil moist. After planting seedlings for 10 ~ 15 days, the color of Ophiopogonjaponicusseedlings turned green and the sun did not wither, which indicated that the planted Ophiopogonjaponicusseedlings had developed new roots and survived.
(7) Intercropping maize: On the same day or later stage of transplanting seedlings of
Ophiopogon japonicus, furrows were opened in the planting field of Ophiopogon
japonicus, and a row was furrowed every 7 ~ 13 rows of Ophiopogon japonicus. Zinc
fertilizer was applied as base fertilizer at the bottom of the furrow, with zinc fertilizer of
1.Okg/667m 2. After covering shallow soil, corn seeds were seeded by direct seeding. The
planting density of maize is 3000 ~ 4000 plants /667m 2, the distance between plants is 20
~ 26 cm, and multiple seeds are sown in a single row.
Wild Ophiopogonjaponicusis born under the forest, so the cultivation of Ophiopogon
japonicus should imitate its wild environment, and consider its biological characteristics to
meet its needs of shade conditions, interplanting other crops in Ophiopogonjaponicusfield.
April to July is the vigorous growth period of corn needs sufficient sunlight, direct light
can be fully utilized in the field, and winter wheat in April is in the seedling stage shortly
after planting, is not suitable for strong light, corn can be shaded, forming a suitable
ecological environment to meet their needs. After corn planting, the roots rapidly extended,
and at this time, Ophiopogonjaponicus with shallow roots began to enter the vegetative
root growth period. Nutrient roots were mainly distributed in the soil layer of 10 cm, and
each other could make full use of the soil strength at different depths to avoid competing
for nutrients in the soil layer at the same depth. After corn harvest, Ophiopogonjaponicus
was in the vigorous growth stage of vegetative roots and tillering seedlings, and the
requirements for increasing light demand could be met.
(8) Intercropping garlic: 10 ~ 15 days before corn harvest, the garlic cloves are
sterilized and planted in Ophiopogonjaponicus field with a row spacing of 40 ~ 50 cm and
a row spacing of 10 ~ 15 cm. After corn harvest, it is the vigorous growth period of
Ophiopogonjaponicus, and the nutrient roots go deep into the lower soil layer, which needs
a certain amount of light. However, garlic seedlings are still in the seedling stage, which
has no effect on the growth of Ophiopogon japonicus, and Ophiopogon japonicus can
flourish and seal before beginning of winter. February-April of the following year is the
peak growth period of garlic seedlings, which is also the key period for root tuber of
Ophiopogonjaponicus to expand rapidly. If garlic seedlings are harvested in time, garlic
will not compete for nutrients of Ophiopogonjaponicus,which will not affect the growth
of Ophiopogonjaponicus,and still make Ophiopogonjaponicusobtain high yield.
(9) Field management: Ophiopogonjaponicus must be watered in time to keep the
soil moist. In case of spring drought and summer drought, water should be poured in time,
and soil cracking should be avoided by all means. When the temperature is high, irrigation
should be done slowly, and flooding should not be too urgent; Drain water in time after
rain. Combined with intertillage and field management, shallow intertillage should be
carried out twice in July-August and September-October, and the depth of intertillage
should be less than 3 cm without damaging roots and plants. Remove weeds in time and
keep the countryside clean. Generally, after planting Ophiopogon japonicus seedlings,
weed once every 15 days, and from May to December, weed once or twice a month; It is
not suitable for weeding from January to February.
Corn: after the emergence of corn, thinning or replanting the seedlings according to
the growth trend; In the late stage of wax ripening of corn, the top and foot leaves are removed in time, that is, the upper straw at 3 ~ 4 leaves on the ear of corn is cut off, and the foot leaves below the ear are removed, showing Ophiopogonjaponicusto facilitate the growth of Ophiopogonjaponicusseedlings; After the corn matures, harvest it in time, and cut off the corn stalks.
