Embodiment approach
[0039] Low nitrate vegetables of the present invention [NO 3 - The cultivation method of -N (mg / kg)≤450ppm.] is shown in Fig. 1; the system for quantitative control of specific natural components of vegetables in this embodiment includes: a nutrient solution supply and recovery system 1 and a Hydroponic planting area 2;
[0040] Referring to as shown in Figure 2, this nutrient solution supply and recovery system 1 mainly supplies or recycles nutrient solution for the vegetables planted in the hydroponic planting area 2; at first this nutrient solution supply and recovery system 1 monitors the vegetables in the hydroponic planting area 2 at any time. The EC value and ph value of the nutrient solution; if necessary, adjust the EC value or ph value of the nutrient solution, so that the vegetables in the hydroponic planting area 2 can obtain the most suitable and sufficient nutrients, which is conducive to the rapid growth of vegetables and improves the unit area. and when the v...

The present invention provides a low-nitrate vegetable planting method, the inspecting quantity of the nitric nitrogen (N03-N) of the vegetables produced by the method is less than 450ppm, namely, the NO3-N (mg / kg) is less than or equal to 450ppm; by using an advanced water planting system and an interrupted nutrient solution supply method, the specification of lower than 450ppm of the inspecting quantity of the nitric nitrogen of the vegetables can be reached; the present invention comprises a nutrient solution and recovery system. Before the harvesting day, a period is set to lead the vegetables to consume(transform) the nitric nitrogen and then recover the nutrition solution; and during the period the clean water which can maintain the basic biological needs is just supplied to cause the vegetables to fully utilize the law of nature of photosynthetic efficiency, so as to consume(transform) the nitric nitrogen accumulated in the plant, thus leading to the nitric nitrogen in the vegetables and plants being far less than the nitric nitrogen contained in the vegetables planed by traditional soil cultivation, water cultivation, wildness or organic cultivation; by using the present invention, the specification of nitric nitrogen of the vegetables which can not self-accomplished under the nature condition is realized and the harmful ingredients in the vegetables is controlled within a rated amount.
Description
1. Technical field [0001] The invention relates to a vegetable cultivation method, in particular to a low nitrate vegetable and a cultivation method thereof. 2. Background technology [0002] Vegetable high nitrate nitrogen (NO 3 - -N) content has adverse effects on human health. It is an issue that has plagued agricultural experts for a long time. It is also a technical problem that the farming and planting industry has not been able to propose effective solutions. So far, few people have focused on the control of vegetable nitrate nitrogen (NO 3 - -N) content issues, let alone technological development and breakthroughs; before the application of the present invention, other than using genetic modification technology to try to change the genes and components of crops (including vegetables), there are very few other targeted vegetables. Experiments or discussions on quantitative control of harmful human components; however, will the agricultural products grown by genetic...
