1. How much will it cost to plant an acre of sunshine roses in greenhouses in 2022?
1, greenhouse investment
Cement columns: 40 cement columns are required per mu, each 30 yuan, and the cost is about 1200 yuan.
Rack surface drawing: 220kg1.8-2mm steel wire is required per mu, and the scrap market purchase price is 2.2 yuan/kg, which costs about 480 yuan.
Tent cloth: about 3400-5 100 yuan is required per mu.
2, seedling investment
The row spacing of the plants planted in the hedgerow of Sunshine Rose Grape is1.5x0.8m, and 150 plants can be planted per mu. The cost of seedlings is 825 yuan based on 5 yuan/plant.
3. Other inputs
Fertilizer needs 500- 1000 yuan per mu, and pesticide needs 200-300 yuan per mu. 300 yuan is required for bamboo chips, 200 yuan for beams, 200-400 yuan for wire drawing, and 100-300 yuan for bird net.
4. Total input: The total input cost per mu is about 7000- 10000 yuan.
Note: Economic conditions vary from place to place and are for reference only.
2. How much can you earn by planting sunshine roses in greenhouses in 2022?
Sunshine rose can naturally set fruit in two years, and the yield can reach more than 0/000 kg per mu/kloc-0. The average weight of each grape spike is 750 g, and the average weight of each fruit is 18 g, without small and stiff fruit. By direct selling, the price of grapes per catty is 25 yuan, and the output value per mu is 50,000 yuan. Average yield of 4-year-old mu 1300 kg.
Generally speaking, the first year of sunshine rose planting is pure investment, and there is no income: the second year begins to bear fruit and produce benefits. Normally, the sales income in the second year will fully saturate all the investment in the first and second years, and the third year will enter high yield and produce high profits.
Third, the cultivation points of sunshine rose in greenhouse
1. Choose sandy loam or loam plot with sufficient light, convenient irrigation and drainage, and deep and fertile soil layer to build the garden. Before planting, dig a planting ditch with a width of 80 cm and a depth of 50 cm, apply sufficient base fertilizer, and apply 2000-3000 kg of decomposed organic fertilizer and 40 kg of calcium superphosphate every 667m2. After mixing the fertilizer with topsoil, apply it to the lower layer of the planting ditch, and then fill the topsoil higher than the ground/kl. At the beginning of February in Nanning, the temperature began to rise, and the plant spacing was 2.8 meters and 5.6 meters, and the flat shed was planted with T-shaped frame.
2. When the new shoots grow to 8 leaves, pick the core. After the secondary shoots grow, select the strong one on the upper part to prolong the growth, and remove the other secondary shoots. Height, width and vertical. In winter, short shoots and extremely short shoots are mostly pruned, resulting in 1-2 buds on the mother branch, and the cutting mouth is 2-3 cm away from the bud eye. After two years, the growth of branches and vines should be controlled reasonably through summer pruning and winter pruning to prevent the bearing parts from moving out.
3, base fertilizer, after the fruit is harvested, dig a deep ditch with a width of 40 cm and a depth of 40 cm at a distance of 50- 100 cm from the plant trunk, and apply 500 kg of decomposed organic fertilizer per mu. Top dressing: Top dressing is carried out in rhizosphere at germination stage, flowering stage, young fruit growth stage and color change stage, with nitrogen fertilizer as the main fertilizer in the early stage and phosphorus and potassium fertilizer as the main fertilizer in the later stage, which can be applied in water or dry, with 40 kg of chemical fertilizer per mu. The number of fruit ears in 4 mu is 2000-2400, the yield per mu is controlled at 1000- 1200 kg, and bagging is about 24 days after flowering.
4, pay attention to the prevention and control of powdery mildew, downy mildew, anthracnose and white rot and other pests and diseases.
In a word, the sunshine rose planted in greenhouse can bear fruit in about 2 years after seedling cultivation, and the average annual output is about 6 10 kg/ha, with high income. After high-yield cultivation, the weight of fruit can be improved in an all-round way, and the positive role of high-yield cultivation techniques can be fully exerted at an average annual yield of 1 100 kg/ha.
