Embodiment Construction

[0028] A method for cultivating leafy vegetables with low nitrate content, the method comprising the following steps:

[0029] (1) Soil preparation 1: Use a small tiller or manually to plow and level the soil in the vegetable field, ditch, and ridge. The ditch width is 25-30 cm, the ditch depth is 15-18 cm, and the ridge width is 120-150 cm. , The length of the ridge is determined according to the field.

[0030](2) Fertilization 2: Apply decomposed farmyard manure, or apply farmyard manure + urea, superphosphate, potassium sulfate fertilizer, or apply farmyard manure + NPK compound fertilizer, or apply NPK compound fertilizer. The amount of fertilizer required to reach nitrogen (N) 90-110 kg / ha, phosphorus (P) 45-55 kg / ha, potassium (K) 45-55 kg / ha. When fertilizing, after applying the fertilizer to the prepared vegetable field, artificially mix the fertilizer evenly into the soil at 1-2 cm.

[0031] (3) Sowing 3: Due to the thick and hard seed coats of the seeds of leafy v...

Abstract

The invention discloses a cultivation method of leaf vegetable with low nitrate content. The method comprises the following steps: A, land preparation: turning over the soil, ditching and ridging; B, fertilization: applying chemical nitrogenous fertilizer potassium, wherein 100 kg of N, 50 kg of P and 50 kg of K are applied to each hectare; C, seeding: seeding the sprouted vegetable seeds into the fertilized soil after the land preparation; D, watering: watering and covering the soil with a thin film or sunshade net after the seeding; E, spraying plant physiological regulator: spraying the prepared plant physiological regulator in the growth period of vegetable, once every week and three in total; F, prevention and control of disease, pest and grass: spraying liquid medicine for preventing disease and killing pest, and weeding in the vegetable plot; and G, harvesting: harvesting the ripe crops. The method is easy to implement and convenient to operate, and has low cost; the plant physiological regulator has good effect and is convenient to use and widely applicable; and moreover, the method is widely applicable to the planting of leaf vegetable in the same type of vegetable plot soil, reduces nitrate content of leaf vegetable, improves the vegetable quality and the soil quality, and prevents widespread pollution caused by excessive soil nutrient.

Description

technical field [0001] The invention relates to the technical field of nitrate and fertilizer effectiveness of leafy vegetables, and more specifically relates to a cultivation method of leafy vegetables such as pak choy, lettuce, radish and water spinach with low nitrate content, so as to reduce the nitrate content of leafy vegetables. Salt content, improve vegetable quality and control agricultural non-point source pollution. Background technique [0002] Vegetables are an important food for people's daily life, but they are easy to accumulate nitrate in soil and cause pollution. Existing studies have shown that 85% of the nitrate absorbed by the human body comes from vegetables. Frequent consumption of vegetables with high nitrate content has a great impact on human health. One of the important indicators. With the long-term and large-scale use of chemical nitrogen fertilizers in vegetable land, not only the nitrate content in the soil is continuously increasing, resulti...
