Problems solved by technology

[0003] The purpose of the crop regulation technology of the present invention is to address the deficiencies in the existing agricultural production models, thereby proposing a regulation method for fertilizing and cultivating crops, fundamentally overcoming the high application of chemical fertilizers in the agricultural production process, and the absorption of fertilizers by crops. Low utilization rate, serious loss of nitrogen and phosphorus in farmland, and pollution of river basin water sources; change the status quo of low yield, poor quality, and instability of agricultural products

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...

Abstract

The invention relates to a crop regulation technique, which comprises fertilization technique regulation and cultivation technique regulation of graminaceous crops such as rice, wheat, corn, broomcorn, tobacco and vegetables among crops. The fertilization technique regulation is realized by adopting two methods, wherein one method is to apply regulating organic fertilizers at roots and keep the application rate to be 50-150kg / mu, without applying other chemical fertilizers at roots during the full growth period of the crops; and the other method is to spray foliar fertilizers with a regulation function and keep the application rate to be 0.8-1.2kg / mu in the full growth period. The cultivation technique regulation is realized through a planting method of further increasing the original conventional planting density of the crops by 10-50 percent. Since not only can the requirement on high-target production of the crops be satisfied, but also the application amount of conventional root-applied chemical fertilizers can be decreased by 50-90 percent, the crop regulation technique has the advantages that the pollution, caused by farmland nitrogen and phosphorus loss, to water bodies of a river basin can be greatly reduced, and the stability of physical and chemical properties of soil and the sustainable production are maintained by additionally applying the organic fertilizers.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to crop regulation technology for crop fertilization regulation and planting regulation. Background technique [0002] At present, the existing agricultural production technology mode, its fertilization method is not scientific and reasonable enough, the application of chemical fertilizers is generally high, and the absorption and utilization rate of crops is low, and there is a serious loss of nitrogen and phosphorus, resulting in water sources in the basin. The phenomenon of pollution makes the physical and chemical stability of the soil poor, and the problem of unsustainable production appears. Although the organic agricultural model advocates the non-application of chemical pesticides and chemical fertilizers, there are low product yields, poor quality stability, and difficulties in the control of crop diseases and insect pests, which affect large-scale applica...
