Cultivation method of Jerusalem artichoke
Looking at the Jerusalem artichoke harvested by your neighbor's house piled up into a hill, are you also wondering how to maintain this cold-resistant crop? As a treasure plant for both medicine and food, Jerusalem artichoke is becoming the new favorite of garden planting due to its superior environmental adaptability and high-yield characteristics. Today, we will start from practical planting experience to unlock the core trick of making Jerusalem artichoke tubers expand. The core maintenance rule for high yield of Jerusalem artichoke is temperature, light and gold ratio. When the temperature stabilizes at 18-22℃, the tubers will enter an explosive growth period. Measured data show that the tuber yield of plants maintained for 12 hours of light per day is 37% higher than that of conventional planting. At noon in midsummer, you can use a sunshade net to filter strong light to avoid leaf burns. The smart watering dual-control strategy adopts the "alternating dry and wet method": water is poured thoroughly when the top layer of the soil is 3 centimeters dry. Before the rainy season comes, 20-cm-deep drainage channels were excavated on both sides of the planting ditch in advance. It is recommended to use red pottery pots for potted plants, which have a 60% higher air permeability than plastic pots. Precision fertilization schedule After topdressing urea in early May, potassium sulfate fertilizer will be used when the plants appear. Here's a tip: Mixing 5% bone meal into fertilizer can increase the starch content of tubers by 15%. Avoid applying undecomposed farmyard manure, which may easily cause root rot. Advanced management skills analysis The three-dimensional planting space plan uses a golden plant spacing of 0.5×0.5 meters, combined with ridging cultivation. A ridge height of 25cm can effectively prevent waterlogging, and combined with black plastic film can inhibit weed growth by 85%. When the vines reach 1 meter long, build a chevron bracket to guide the climb. During the three elements of pruning art, the focus is on pruning the bottom yellow leaves to ensure ventilation and light transmission. Cutting off residual flowers immediately after flowering can reduce nutrient consumption by 23%. If branches are found to be too dense, they must be pruned decisively to maintain the ideal plant type of "three branches and nine tops." The cultivation method of Jerusalem artichoke is a practical plan for pest and disease control. Rust prevention and control is three-step approach. During the early spring germination period, spray 15% triadimefon wettable powder 800 times. Remove the sick leaves immediately and spray the back of the leaves with plant ash water every week. Keeping no weeds accumulating within 3 meters around the planting area can reduce the risk of bacterial transmission by 78%. For pest emergency treatment, a natural formula of pepper water + detergent can be used for aphids, and the ratio is 500:1. It is recommended to kill and kill moth larvae manually. During peak periods, yellow sticky insect boards are hung, and 30 pieces are placed per mu of land for the best effect.
Through the above systematic management, novices can also grow fist-sized Jerusalem artichoke. Remember to keep the soil slightly moist during tuber expansion and stop watering 20 days before harvest. Practice these methods now and look forward to you harvesting a basket full of "underground gold" in the autumn!
