Winter potato balanced fertilization expert system based on target yield

Abstract

The invention relates to the technical field of potatoes, and discloses a winter potato balanced fertilization expert system based on target yield, which comprises a potato planting system, and the potato planting system comprises a soil preparation system, a seeding system, a fertilization system and a weeding system. Based on the fact that 4.14 kg of pure nitrogen (N), 2.34 kg of phosphorus (P2O5) and 8.74 kg of potassium (K2O) need to be absorbed when 1000 kg of fresh potatoes are produced, and according to a balanced fertilization target yield method, the total fertilization scheme is as follows: under the condition that 400-600 kg / mu high-quality commercial organic fertilizer or other high-quality decomposed organic fertilizer containing equivalent nutrients is applied, the fertilizer application scheme is shown in Figure 6, wherein the fertilizer dosage in the figure 6 is determined according to the nitrogen-potassium fertilizer power of the soil at medium and low levels; N dosage is firstly determined; the amount of phosphorus-potassium fertilizer is determined by using nitrogen to determine phosphorus and potassium; the actual application amount should be properly adjusted according to the local soil fertility condition and the planting mode, so that the high-yield, high-quality and high-efficiency effects of the winter-cropping potatoes are achieved.

Description

technical field [0001] The invention relates to the technical field of potatoes, in particular to an expert system for balanced fertilization of winter potatoes based on target yield. Background technique [0002] Potatoes, belonging to the family Solanaceae, are annual herbaceous plants with edible tubers. They are the fourth most important food crop in the world, second only to wheat, rice and corn. Potatoes are also known as yams, yams, yams, fragrant yams, yams, mountain yams, yams, ground eggs, potatoes, etc. (also known as yams in Datong, Shanxi). In some southern provinces, it is also called "winter potato", because it is often planted in winter after harvesting autumn rice. [0003] At present, the existing potato planting methods on the market are different in different places, resulting in different potato yields in different places. The yield of potatoes is closely related to the growth environment of potatoes. So the elements in the fertilizer have a great impa...

Problems solved by technology

[0003] At present, the existing potato planting methods on the market are different in different places, resulting in different potato yields in different places. The yield of potatoes is closely related to the growth environment of potatoes. In order to meet the elements needed for the growth of potatoes, generally in potatoes So the elements in the fertilizer have a great influence on the yield of potatoes, so generally too much fertilizer is applied to the potatoes, which easily leads to waste of fertilizers. At the same time, it may also reduce the yield of potatoes due to the excess nutrition of the potatoes
