Embodiment 1
[0023] A yam planting method for overcoming continuous cropping obstacles, comprising the following steps: (1) on a yam planting land of 5 mu, plant the yam rhizomes that have reached the harvest period in the first year in the original hole, and plant them in the second year;
[0024] (2) In the soil area within the radius of 10cm with the rhizome as the center, do not loosen the soil, water, or fertilize, and try to keep the soil state in this area from being damaged;
[0025] (3) At the beginning of November of the second year, the harvest can be carried out, and the harvest volume will be 30,000 jin. Calculate the average annual yield of yam for two years to be 3000 catties, and the quality of yam is 0.01% allantoin, 0.12% yam saponin, and 22% yam polysaccharide.
Embodiment 2
[0031] A yam planting method overcoming continuous cropping obstacles, comprising the following steps:
[0032] (1) On the 5-acre yam planting land, the yam rhizomes that have reached the harvest period in the first year are left in the original hole for planting in the second year;
[0033] (2) In the soil area within a circle with a radius of 10cm centered on the rhizome, do not loosen the soil, water, or fertilize, and try to keep the soil state in this area from being damaged.
[0034] (3) When fertilizing the yams used for planting in the previous year in the second year, the horizontal distance between the fertilization position and the planting should be at least 10cm. Fertilization time is early April, and the amount of fertilizer is applied to each hole containing 0.3% KH 2 PO 4 and 0.5% KNO 3 Composite aqueous solution 0.5Kg.
[0035] (4) At the beginning of November of the second year, the harvest was carried out, and the harvest volume was 33,000 jin. Calculat...
Embodiment 3
[0037] A yam planting method overcoming continuous cropping obstacles, comprising the following steps:
[0038] (1) On the 5-acre yam planting land, the yam rhizomes that have reached the harvest period in the first year are left in the original hole for planting in the second year;
[0039] (2) In the soil area within a circle with a radius of 10cm centered on the rhizome, do not loosen the soil, water, or fertilize, and try to keep the soil state in this area from being damaged.
[0040] (3) In the second year, apply EM engineering bacteria around the planted rhizomes, and the horizontal distance between the position where the EM engineering bacteria is applied and the planting is at least 10cm. The time for applying EM engineering bacteria is early May, and the amount of application in each hole is 0.5Kg.
[0041] (4) At the beginning of November of the second year, the harvest was carried out, and the harvest volume was 34,000 jin. Calculate the average annual yield of y...
