(1) The formulation of cultivation management regulations mainly determines the types of vegetables suitable for planting, variety combinations and market launch periods based on market needs and price conditions, and formulates technical operation procedures for sowing and seedlings, planting density, plant shape control, etc. .

(2) The formulation of nutrient management regulations takes the three elements of nitrogen, phosphorus and potassium as the main indicators for fertilizer supply. The fertilizer applied per 1 m3 of substrate should contain: total nitrogen (N) is 1.5~ 2.0 kg, total phosphorus (P2O5) is 0.5-0.8 kg, and total potassium (K2O) is 0.8-2.4 kg. This level of fertilizer supply is enough to meet the nutrient requirements of 8,000 to 10,000 kilograms of tomatoes per crop of 667 m2. In order to maintain optimal fertilizer supply throughout the entire growth period of crops, fertilizers are usually applied in stages depending on the type of crop and the fertilizer applied. Before filling the cultivation groove with the substrate, or after the previous crop is harvested, or before the subsequent crop is planted, a certain amount of fertilizer should be mixed into the substrate as base fertilizer, so that tomatoes, cucumbers and other fruits and vegetables do not need to be topdressed within 20 days after planting. , just water it, and topdress every 10 to 15 days after 20 days, and spread it evenly around 5 cm away from the roots. The ratio of base fertilizer to top dressing is 25:75 to 60:40. The amount of top dressing per 1 m3 of substrate each time: 80 to 150 grams of total nitrogen (N), 30 to 50 grams of total phosphorus (P2O5), and 50 to 180 grams of total potassium (K2O). The frequency of top dressing depends on the length of the growing season of the crop.

(3) Formulation of water management procedures: Determine the irrigation quota according to the type of cultivated crops, and adjust the amount of each irrigation according to the moisture content of the substrate during the growth period. The day before planting, the amount of water should be enough to reach the saturated moisture content of the substrate, that is, the substrate should be watered thoroughly. After the crops are planted, the number of irrigations per day varies, once or 2 to 3 times a day to maintain the moisture content of the substrate at 60% to 85% (accounting for dry substrate). Generally, in the adult stage, cucumbers are watered 1 to 2 liters a day, tomatoes are watered 0.8 to 1.2 liters, and bell peppers are watered 0.7 to 0.9 liters a day. The amount of watering must be adjusted according to climate changes and plant size. Irrigation should be stopped on cloudy and rainy days, and irrigation should be done every few days in winter.
