specific Embodiment approach 1
[0023] Embodiment 1: The planting method for densely planting rice in one hole and multiple plants in saline-alkali land of the present embodiment is carried out according to the following steps:
[0024] 1. Raising seedlings: Choose rice seeds with strong salinity and alkali resistance and suitable for local climatic conditions in the mature period for dry-greenhouse seedlings. Seedlings 2 to 3 days;
[0025] 2. Land preparation: rotary tillage in early spring, the depth of rotary tillage is 15-20cm, soak the field for 7-9 days before planting, and the water depth of the soaked field does not exceed 5cm, and then apply nitrogen, phosphorus and potassium compound fertilizer as the base fertilizer, and the amount of fertilizer is 500-600kg / ha , at the same time, perform mechanical raking, raking to leveling, after raking is completed, change the water 1-2 times, the water depth does not exceed 5cm, and then let the soil naturally settle to the water surface to clarify;

specific Embodiment approach 2
[0034] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in step 1, the amount of seeds used for seedling raising is 80 kg / ha, the growth period of the seedbed is 40 days, and other steps and parameters are the same as those in Embodiment 1.
specific Embodiment approach 3
[0035] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the depth of rotary tillage in Step 2 is 15 cm, and other steps and parameters are the same as Embodiment 1 or 2.
