Embodiment 1
[0013] Take the regulated planting of wheat grown in the north as an example of gramineous crops:
[0014] 1. Apply 100kg / mu of organic fertilizer with a regulating effect on the root, and its total nutrient content of nitrogen, phosphorus and potassium is 4%. 2 o 5 11,K 2 O8) Compared with the total amount of 29kg / mu, it accounts for 13.8% of the industry's conventional, a decrease of 86.2%. It is the total amount of application during the whole growth period, and it is used as a base fertilizer at one time when sowing;
[0015] 2. Foliar spraying with foliar fertilizers with regulatory effects, the spraying amount in the full growth period is 1.2kg / mu, and the concentration of the sprayed fertilizer solution is 5‰, which is carried out in three times; 10% of the total amount of spraying in the leaf stage; 40% of the total amount of spraying at an interval of 20 days for the second time; 50% of the total amount of spraying at an interval of 20 days for the third time;

Embodiment 2
[0018] Crop regulation technology takes flue-cured tobacco planted in the south as an example:
[0019] Root application regulation: its root application has a regulating effect. Organic fertilizer 120kg / mu, containing total nutrients (N+P 2 o 5 +K 2 O) is 10%, and the total nutrient amount per mu is 12kg / mu, which is (N6.5, P 2 o 5 14,k 2 O24) with a total amount of 44.5kg / mu, accounting for 27% of the industry's conventional total nutrients, a decrease of 73%; used as a base fertilizer when transplanting tobacco seedlings into the field. The foliar fertilizer spraying is carried out in four times, the total application rate is 1.0kg / mu, and the concentration of the spray solution is 4‰ after adding water. The first spraying time is 7 days after transplanting; the second spraying time interval is 15 The third spraying time is carried out at an interval of 15 days; the fourth spraying time is carried out at an interval of 20 days; the first application is 10% of the total...
Embodiment 3
[0021] Farming as a control technology takes the cultivation of cabbage in the north as an example:
[0022] Apply 150kg / mu of organic fertilizer with regulating effect on the root, and its total nutrient (N+P 2 o 5 +K 2 O) is 8%, and the total nutrient level is 12kg / mu, which is the same as the total nutrient (N25, P 2 o 5 7,k 2 O24) amount is 56kg / mu, accounting for 21% of the industry's conventional total nutrients, a decrease of 79%; When transplanting the field, it is used as a one-time application of base fertilizer; foliar fertilizer control: the foliar fertilizer spraying is carried out in four times, and the seedling stage is sprayed for the first time, and 0.05kg is sprayed on the nursery according to the number of seedlings per mu in the field. Use within one week before planting, spray three times in the field period, spray once 7 days after transplanting, apply fertilizer at a rate of 0.25kg / mu, spray twice at intervals of 15 days, use fertilizer 0.3kg / mu, an...
