The asexual reproduction process of artichoke (also known as potato) must pass through three growth stages: germination, seedling and germination. When the temperature reaches 4 °C, it can germinate, and the growth rate of buds is the fastest at 13 °C. The optimum temperature for stem and leaf growth is 21 °C, the optimum temperature for stem formation, 14 °C - 24 °C during the day, and 12 °C - 17 °C during the evening. Short daylight and strong light are beneficial to tuber enlargement, but the temperature is too high. The tubers are small. Planting spring sowing mulch must choose a land with good drainage and irrigation conditions, deep ploughing, and fertile and loose soil. Linyi Fertilizer Network Copyright

First, the nutrition and fertilizer requirements of artichoke: Linyi Fertilizer Network Copyright

Artichokes are potassium-producing crops, which require the most potassium fertilizer during the whole growth period, followed by nitrogen fertilizer and phosphate fertilizer. But the ingredients are different in different growth stages of artichokes. Linyi Fertilizer Network Copyright

Nitrogen fertilizer can make the stems and leaves grow lush, the leaves are dark green, the photosynthesis is strong, the accumulation of organic matter is increased, and the protein content is increased. If it is excessive, the plants will grow wild in the late growth stage, the maturity period will be delayed, and the yield will decrease. Linyi Fertilizer Network Copyright

Phosphate fertilizer can promote the growth of plants, improve tuber quality and storability, and increase starch content and yield. In the absence of phosphorus, the dwarf leaves are small, the photosynthesis is weakened, the yield is reduced, and the potato pieces are hollow, rust, hardened, and poorly cooked. Excessive phosphorus, enhanced respiration of crops, large consumption of phosphorus compounds, thick and dense leaves, premature development of systemic organs, inhibition of stem and leaf growth, easy to cause premature aging. Water-soluble phosphates can form compounds with low solubility with elements such as zinc, iron, and magnesium in the soil, reducing the effectiveness. Linyi Fertilizer Network Copyright

Potassium fertilizer can enhance the disease resistance and cold tolerance of plants, accelerate the operation of nutrients, and increase the starch and vitamins in tubers. Insufficient potassium, growth is inhibited, the aerial part is dwarfed, the internodes are shortened, the plants are clustered, the leaves are small and dark green, and gradually become bronze, until the dead, the tubers are mostly elongated or spindle-shaped.

Boron is beneficial to tuber swelling and crack prevention, and has a special effect on improving the net photosynthetic productivity of plants. Linyi Fertilizer Network Copyright

Copper can increase the protein content, enhance the respiration of plants, increase chlorophyll content, delay leaf senescence and drought resistance, and improve plant net photosynthetic productivity. Linyi Fertilizer Network Copyright

Calcium and magnesium increase with the expansion of tubers, and the absorption of inorganic components of magnesium accounts for about 50%. Linyi Fertilizer Network Copyright

Second, the arterial fertilization technology points: Linyi Fertilizer Network Copyright

Base fertilizer: 80% of the fertilizer in the growth period of the artichoke is derived from the base fertilizer, and the application of the base fertilizer must be emphasized in cultivation. If the base fertilizer is insufficient, it is necessary to apply fertilizer during the sowing period. Linyi Fertilizer Network Copyright

Topdressing: The seedling stage of the artichoke is short, and it is the foundation period for rooting and planting. Seedlings and early catching fertilizer, 15-20 kg of quick-acting nitrogen fertilizer per acre, scattered between rows, cultivating and watering. Into the flowering period, see the flower buds can apply 20 kg of potassium sulfate per acre to prevent premature aging. The potato season depends on the growth. Stem and leaves prematurely yellow, can be a small amount of nitrogen fertilizer, or foliar spray fertilizer, no longer topdressing after sealing the ridge. Linyi Fertilizer Network Copyright

Third, the fertilization standard and formula of the artichoke Linyi Fertilizer Network Copyright

According to the principle of total nutrient fertilization, in addition to the application of nitrogen, phosphorus and potassium, it is necessary to pay attention to the application of medium and micro-element fertilizers to meet the normal, high-quality and nutrient growth requirements of artichokes and obtain high yield. The spring sowing mulch is about 2000 kg, and the fertilization formula is as follows: Linyi Fertilizer Network Co., Ltd.

1. Seed potato compost: After cutting the seed potato, mix it directly with “Saizhong 28” fertilizer. Linyi Fertilizer Network Copyright

2. Base fertilizer: 1 urea 10-15 kg, diammonium 7.5-10 kg, potassium fertilizer 20-25 kg, "Saizhong 28" fertilizer 28.25 kg; 2 hydrogen ammonia 40-60 kg, phosphate fertilizer 38-50 kg, potassium fertilizer 20-25 kg , "Saizhong 28" fertilizer 28.50 kg. Linyi Fertilizer Network Copyright

Hole storage fertilizer water film cover technology Linyi Fertilizer Network Copyright

Acupoint storage of fertilizer and water is a simple and easy-to-use, low-yield, water-saving and drought-resistant technology with the characteristics of fertilizer and water saving. The application effect is particularly remarkable in hilly areas where the soil layer is thin and waterless. The specific operation technology is as follows: Linyi Fertilizer Network Copyright

The crop straw or weeds are bundled into grass pieces with a diameter of 15 to 25 cm and a length of 30 to 35 cm, which are soaked in water or 5% to 10% of urine. At the edge of the canopy projection 50 to 70 cm inward, a storage hole with a diameter slightly larger than the grass handle is drilled (the pit is rounded around the root). According to the size of the crown, the number of storage points is determined. The crown diameter is 3.5 to 4 meters, and 4 holes are dug; the crown diameter is 6 meters, and 6 to 8 holes are dug. Place the grass in the center of the hole, and use the soil with mixed organic fertilizer to step on it (5 kg of soil per pot, add 150 g of superphosphate, 50-100 g of urea or compound fertilizer), and water it in moderation. Then tidy up the tree tray so that the nutrient points are 1 to 2 cm below the ground and form a plate. Each hole is watered for 3 to 5 kg to cover the film. Cut the old agricultural film and flatten it, cover it on the tree plate, and make sure that the nutrient hole is covered under the film, and the soil is compacted around and in the middle. Each hole covers 1.5~2 square meters of mulch film. The edge of the film is pressed with soil pressure. The center is drilling a small hole in the upper end of the grass, and it is blocked by stones or soil, so that it can be used for watering or receiving rainwater in the future. Generally, after flowering (mid-May), new shoots stop growing (mid-June) and three periods after fruit picking, 50-100 grams of urea or compound fertilizer is applied to each hole, and the fertilizer is placed on the top of the grass. Watering about 3.5 kg. Enter the rainy season, remove the mulch and store the rainwater in the cave. Generally, the storage hole can be maintained for 2 to 3 years, and the grass should be changed once a year. It is found that the film is damaged and replaced in time. When the storage hole is set again, the position is changed and the whole garden is gradually improved. Linyi Fertilizer Network Copyright
