Breeding and planting techniques of Polygonatum polygonatum

1. Seed breeding first soak the seeds of Polygonatum polygonatum in clean water for about a month, put them in a cool place to dry, then refrigerate the seeds in the refrigerator for a month, then sprinkle the seeds on the soil, control the temperature at about 18 ℃, and pour water every other week to wait for the seeds to germinate.

2. Topdressing: when Polygonatum seeds grow leaves, ventilate the plastic greenhouse every day, water it in the morning and evening, keep the matrix humidity 30% Mel 40%, and spray potassium dihydrogen phosphate compound fertilizer solution every other week. (2) weeding: Rhizoma Polygonatum seedlings should be weeded once a month during the growth period. Polygonatum seedlings are not tolerant to grass pressure, so they should be pulled up as soon as they see the grass when they are raised, so that they can be removed early, small and clean.

3. Polygonatum planting technology land selection and fertilization (1) first of all, we must choose sunny, fertile, well-structured land that will not accumulate water. Polygonatum does not like the sun very much and must be shaded properly at the seedling stage. (2) it is necessary to prepare a sunshade net when planting for 1 month, which can reduce sunlight and protect seedlings.

4. Conservation method soil: plant Polygonatum in sandy loam or loose soil with good water retention. Because Huang Jing likes cool, moist soil, apply some farm manure before planting, and then plough the cultivated land, which is helpful to promote the absorption of nutrients after planting. Moisture: keep the soil moist at all times for fear of drought. Drain water on rainy days so as not to accumulate too much water and rot the roots.

Generally speaking, only high-quality varieties have a good price. The growth of Polygonatum polygonatum is generally divided into several stages: breeding, seedling raising, growth and maturation. At each stage, there is a big gap in the demand for temperature, water, light, fertilizer and other factors. If there is no room in the middle, it may come out in the future and need to be adjusted in real time according to the growth trend, which is the difficulty in planting technology and management, and there are many things to learn. There are many diseases. The second is the disease.

6. Polygonatum varieties adapt to the climate of southern China, have strong disease resistance, high survival rate and fast growth. Qualified growers can apply for seedling supply from Hubei New Hope Ecological Agriculture Polygonatum planting Investment Company. For growers who sell the finished products to the company, they can get preferential treatment for the supply of seedlings. The grower shall receive one-to-one technical training from the company's technical personnel to learn the techniques of seedling cultivation and grafting tissue culture.

Planting techniques and benefits of Rhizoma Polygonatum

In the planting technology of Huangjing, the sandy land with loose soil and good water conservation effect is selected as the planting land (the land which is too consolidated, water seepage and poor air permeability can not be used as the planting land), and then turn the soil deeply. In order to create a good growing environment for Polygonatum.

Select the land with loose soil and certain water conservation capacity as the planting site, then cut the rhizome of Polygonatum into several segments, each section should retain 3-4 nodes; the root segments should be dried and planted in the planting land, and then irrigated with appropriate amount of water after planting. The benefit of planting Polygonatum polygonatum: the benefit of extensive planting is about 3000 yuan per mu, and the benefit of fine planting is about 60000 yuan per mu.

First, the benefit of Huangjing per mu. Rhizoma Polygonatum, also known as chicken head Polygonatum, its rhizome used in medicine, with yin, essence and other functions, the main treatment of kidney deficiency essence deficiency. It is planted all over the country, and it is planted in the same year. Three years later, the yield per mu can reach 1200 jin, which is calculated according to the price of 58 yuan per kilogram of Polygonatum this year. The benefit of yield per mu can reach 30000 yuan. Second, the market prospect.

How can Huangjing plant high yield per mu?

To plant Rhizoma Polygonatum, the first thing is to choose a place. It is necessary to choose land with deep, loose and moist soil strata. Before planting, you should apply enough fertilizer per mu of land, the best amount per mu is about 2500 kg, after continuous deep ploughing, the depth should be 25 to 30 cm deep. After deep ploughing, a ridge with a width of 2 meters is made.

In general, the yield per mu of Polygonatum polygonatum is about 3000 to 4000 jin. If the planting method of raising seedlings and transplanting is adopted, 5000 to 6000 Polygonatum polygonatum need to be planted per mu. After three years of planting, the yield per mu is about 5000 to 6000 jin. It should be noted that the yield per mu of Polygonatum polygonatum will be affected by soil fertility, climate, management and other factors, so the specific yield may be different.

The yield of Polygonatum polygonatum for 3 years: dry goods 6-1000 jin / mu, high-yield 1200 jin / mu, fresh goods 3000-5000 jin. If Rhizoma Polygonatum wants to have a high yield, it is necessary to choose plots with moist, shady, good drainage, deep and fertile soil, loose soil and convenient irrigation for artificial planting, and avoid continuous cropping. The plots in which Polygonatum polygonatum and seedlings were planted in the previous year can not be used as seedling fields. Rhizoma Polygonatum should loosen the soil and weed in time after emergence to keep the border free of weeds.

Planting methods and techniques of Rhizoma Polygonatum

Rhizoma Polygonatum planting technique (1) the land preparation should choose the land under moist and shady conditions, and the soil should be loam or sandy loam with loose texture and good water retention. Ploughing the soil before sowing, raking fine and leveling, and making beds.

Land selection and land preparation: select sandy loam with deep soil layer, loose and fertile soil and good drainage, deep ploughing and careful cultivation, combined with soil preparation to apply sufficient base fertilizer. Reproduction methods: the reproduction mode of Polygonatum polygonatum includes seed reproduction and plant reproduction, seed reproduction needs to wait for seeds to mature and harvest and sow, and ramet propagation can be carried out in spring or autumn. Field management: farm manure is the main fertilization, properly combined with chemical fertilizer, weeding should be ploughed during the growth period, and drainage should be paid attention to in the rainy season.

The cultivation of Rehmannia glutinosa needs loose and fertile soil, good air permeability and drainage. Can use humus soil, garden soil, humus soil. Turn deeply before sowing, combined with two tons of farm manure per mu of land preparation, turn it into the soil as base fertilizer, and then rake flat to make a bed 1-2 meters wide. Planting method (1) sowing and planting. Choose seeds that grow well and sow them in August.

Rhizoma Polygonatum planting method to select land preparation: Polygonatum planting to select moist and fully shaded plots, the soil should be loam or sandy loam with loose texture and good water retention, combined with 2000 kg of farm manure per mu to be turned into the soil as base fertilizer to ensure the softness of the land, and then rake fine leveling to make the border.

Cultivation techniques of Rhizoma Polygonatum

1. Land selection and preparation: select the land with moist and shady conditions, and the soil should be loam or sandy loam with loose texture and good water retention. Ploughing the soil before sowing, raking fine and leveling, and making beds.

2.-when preparing the soil, it is necessary to dig deep into the soil and remove weeds and stones, so as to create a clean and tidy environment for the cultivation of Polygonatum. * * mode of reproduction *:-Polygonatum is mainly propagated by rhizome for seed expansion. In the harvest season, the 2-3-year-old Rhizoma Polygonatum rhizome with bud head was selected as the seed. Cut off 2-3 segments of the young part of the rhizome and pay attention to keep the incision flat to avoid damage to the bud eye.

3. Generally speaking, the cultivation techniques of Polygonatum polygonatum include land selection and preparation, breeding methods, planting management, harvest processing and so on. Each link needs to be carefully operated and managed to ensure the quality and output of Polygonatum.
