Water and fertilizer management technology of agaric

1. Tillage and fertilizer and water management: generally, tillage and weeding should be carried out after slow seedling, on the shelf and after each harvest, and soil should be properly cultivated at the base of the plant.On the basis of sufficient basal fertilizer, rapid nitrogen fertilizer should be applied for many times during the growth period. Generally, urea and potassium compound fertilizer should be applied for 15kg and 5-8kg for every 667m and 5-8kg for every 667m after seedling fixation, and then the fertilizer should be applied for 15kg for every 667m after picking.Luo kui is fond of wetness and should be irrigated with small amount of water frequently to keep the soil in a moist state. Generally, it is necessary to irrigate the soil with water once per harvest combined with fertilizer application, and increase the number of irrigated times in case of drought.

2. When the seedling height is 30cm, 3-4 leaves are left to pick tender shoots, 2 strong lateral buds are left, and the rest are erased. After the second harvest, 2-4 strong lateral buds are left.5-8 strong lateral buds can be selected in the growth stage.Bud should be wiped out at any time in middle and late stage;At the end of harvest, the growth potential of the plant was weakened and 1-2 strong lateral buds were selected. This kind of management was conducive to the hypertrophy of leaves, strong shoot and fat stem, good quality and high yield.
