High efficient cultivation techniques of Jinluo Stone and Control of main Diseases and insect pests

How does gold broccoli reproduce? How to breed gold brocade stone? Recently, many flower farmers have asked questions about the planting technology of gold mulberry, so the following Huinong network editor has compiled the breeding methods and pest control cultivation techniques of gold mulberry for everyone.

1 Spike nursery

1.1 Land preparation and soil improvement

Choose loose, fertile, slightly acidic, neutral and slightly alkaline soil, improve the clay and soil with insufficient fertility, apply sufficient base fertilizer, apply decomposed organic fertilizer 3000kg per mu, and add phosphorus fertilizer 50kg. To prevent underground pests, pesticide carbofuran 2kg/mu can be applied. The first tillage adopts deep tillage, the depth is more than 25cm, and then fine harrow once; the second tillage requires the bed surface to be flat.

1.2 ditching bed

The central part of the field is low and the two sides are high. The middle ditch is opened in the center of the field and communicates with the side ditch. The depth is 40~60cm and the width is 50~60cm. Make bed: bed surface width 110cm, bed surface clods fine, bed surface middle slightly higher, both sides slightly lower. A footpath is opened between each seedbed, 25cm deep and 40cm wide, so that the ditches are communicated and the drainage is smooth.

1.3 pruning and transplanting

Before transplanting, the aboveground part should be pruned to keep the height of 15cm, so as to promote the germination of new shoots at the base. Transplanting time is 2 ~ 3 months, adopting half-gallon container seedlings to transplant, planting 3 plants horizontally in seedbed, plant spacing is 35cm, row spacing is 40cm, and 3000 plants are planted per mu. Transplanting depth is moderate, slightly deeper than the original plant rhizosphere depth, and then cover the base of the seedlings with fine soil, gently compacted.

1.4 post-planting management

On the day of transplanting, water should be poured thoroughly. In case of continuous sunny days, water should be poured on the 4th day after transplanting, and water should be poured every 10 days thereafter; in case of rainy days, water should be drained in time, and full light management should be carried out to promote lignification. Fertilization begins 15 days after transplanting, urea is applied in April, compound fertilizer is applied from May to September, and the application rate is 15kg per mu every 15 days. No more topdressing after October. Dec. or January of the following year, apply decomposed organic fertilizer once, with the dosage of 1500kg per mu, and apply it between plants in shallow furrows for buried application. After rain sunny days, combined with fertilization to timely loosen weeds, to prevent soil surface hardening.

1.5 disease Control

From April to July, brown spot disease often occurs, damaging leaves, appearing disease spots, gray mold layer on disease spots, when there are many disease spots on leaves, they will fall off ahead of time in autumn. Control methods: remove diseased leaves and burn them intensively; apply organic fertilizer to strengthen tree vigor, ditch and drain in time to improve disease resistance; properly thin seedlings to increase light transmittance; spray 600 ~ 700 times solution of 75% chlorothalonil WP or 500 times solution of 50% carbendazim WP or 800 times solution of 50% sulfur suspension at the early stage of disease, spray once a week and continuously spray 2~3 times.

1.6 and rejuvenating

In order to enhance the vigor of spike, strong pruning must be adopted for female parent plants over 6 years old. In February of the current year, the height of female parent plants should be kept 10cm for stubble cutting. Then loosen the soil and cultivate the soil in time, and apply the decomposed organic fertilizer for one time, with the dosage of 2000kg per mu, to promote the germination of adventitious buds at the roots, generate clump plants, and achieve the purpose of rejuvenation.

2 Breeding and seedling raising

2.1 snipping strip

In early June, the semi-lignified branches of the current year were cut in the morning, and the branches and spikes were cut on the same day. The length of spikes was 3.5cm.

2.2 substrate formula

Peat: vermiculite: pearlite: yellow soil = 6 ∶2 ∶1 ∶1 (volume ratio), dry bulk density 0.30, total porosity 54.89%, macroporosity 15.25%, microporosity 39.64%, maximum water retention 1.82. pH 5.43, EC 0.51 mS/cm, TN 1.99%, TP 323.13 mg/kg, TN 8360.77 mg/kg, Ca 1548.18 mg/kg, Mg 1659.28 mg/kg, Cu 16.77 mg/kg, Zn 54.92 mg/kg, B 180.88 mg/kg, Fe 5256.12 mg/kg, Mn 170.39 mg/kg, Mo 3.39 mg/kg, Al 13633.50 mg/kg, Lead 14.23 mg/kg, sodium 2266.71 mg/kg, nickel 26.87 mg/kg, sulfur 1358.16 mg/kg.

2.3 Disinfectant and plant radicalizer

The matrix in the mesh bag or tray should be watered one day in advance. A net bag tray or a tray with 128 holes is adopted, the seedbed width is 100cm, 3 hole trays are placed longitudinally, 6 ears per square meter and 432 ear strips are arranged, the bed surface is paved with cloth, potassium permanganate 600 times solution is used for disinfection, and a film is used for covering for 24 hours. The plant rooting agent used is naphthylacetic acid 5+GA4 gibberellin 2+ABT6 rooting powder 3, concentration 500ppm, quick dip 2 seconds. Each hole of each net bag or hole plate cuttings 1 spike, cutting depth 2cm, vertical cutting, after cutting is completed, water is poured thoroughly, after the leaf surface is dried, carbendazim 1000 times solution is sprayed on the leaf surface to prevent brown spot.

2.4 post-insertion management

On the day of cuttage, water shall be poured into each seedbed immediately after planting, and after the moisture of leaf surface evaporates, spray pesticide for disinfection and disease prevention immediately, and then set up small arch shed, cover with film, seal around, and keep the relative humidity of air in the shed above 95%. A sunshade net is erected above the seedbed in advance, covering one layer in June and two layers in July and August. Hang a stick thermometer in the small arch shed. When the temperature in the small arch shed reaches above 38℃, spray cooling measures should be taken, especially in sunny days and high temperatures. Spray once every half hour from 10:00 a.m. to 4:00 p.m. to reduce it to below 38℃. Check the humidity of the substrate frequently, and pour water once every 7 ~ 10 days in the evening or early morning. After watering on the cutting day, spray foliar fertilizer with 1000 times solution of chlorophyllous powder or 0.2% urea spray.

2.5 seedling hardening

After 30 days of cuttage, about 90% of the shoots can be cultivated. In the evening, the two ends of the film are removed and ventilated for 2 days, and then all of them are removed. After the film is removed, full light management is implemented. Timely watering and foliar fertilizer spraying, watering once every 15 days or so, spraying foliar fertilizer at the same time, spraying with 0.2% urea.

The roots, stems, leaves and fruits of Chinese starwort can be used for medicinal purposes. They have the effects of expelling wind and activating collaterals, benefiting joints, stopping bleeding, relieving pain and swelling, clearing away heat and toxic materials.

Cultivation techniques of trachelospermum chinensis

(1) Seedling technology: In July, the young shoots with strong growth and aerial roots can be cut, and the layering propagation can be carried out. The layering depth is 3cm, and then moved to the semi-shade for maintenance. The next year, the rooted layering can be dug for transplantation.

(2) Planting technology: select sandy loam with good drainage and transplant with soil ball. Pot planting requires light soil. After planting, water to keep the soil moist. Spray water on branches and leaves frequently to increase humidity. Set up supports in time for climbing. During the growth period, fertilizer and water should be applied once or twice a month to avoid direct sunlight. Proper pruning, maintain good plant type.
