Fertilizer and planting and fertilizing method for potatoes

Abstract

The invention provides a fertilizer and a planting method for potatoes and belongs to the technical field of agricultures. The fertilizer for potatoes comprises a base fertilizer and an additional fertilizer; the base fertilizer contains farmyard manure, plant ash and a phosphate fertilizer which are in the weight ratio of 1:1:0.5 to 3:1:0.3; the additional fertilizer is a diluent obtained by dissolving a nitrogen-potassium chemical fertilizer into a mixed solution of liquid traditional Chinese medicines and carrying out dilution with water according to the ratio of 1: (20-30); the liquid traditional Chinese medicines decocted by using traditional Chinese medicines corresponding to traditional Chinese medicine residues, and the weight ratio of the liquid traditional Chinese medicines to the traditional Chinese medicine residues is (8-10):1. The planting method of the potatoes comprises the following steps: ditching; groove paving; soil filling; planting; and field management. By usingthe fertilizer and the planting method for potatoes, not only is the fertilizer efficiency of soil improved, but also soil hardening or salinization is avoided, the yield of potatoes planted once andthe yield of potatoes planted repeatedly are also guaranteed, meanwhile, the damage of the potatoes is also reduced in a digging process, and the labor cost is reduced; and the potatoes can be repeatedly planted, so that the economic benefit is effectively increased.

Description

Technical field [0001] The invention relates to the technical field of agriculture, in particular to a potato fertilizer and a method for planting and fertilizing the potato. Background technique [0002] Potatoes have played a huge role in providing nutritious food, ensuring food security, improving energy security, helping farmers get rid of poverty and becoming rich, and promoting the development of winter agriculture. Therefore, potatoes can get the attention of all countries in the world, especially developing countries. Play a greater role in the rural economy. Globally, potato accounts for only 2% of the world's average dietary energy supply, but it is the staple food of many countries. In developed countries, potatoes can provide 540kJ of energy per person per day. In developing countries, the figure is about 170kJ per person per day. In addition to providing energy for the human body, many varieties of potatoes also contribute a certain amount of dietary fiber, ascorbi...

Problems solved by technology

However, at present, the development of the potato industry is severely restricted by problems such as backward fertilization technology, single variety, and disease control. The problem of backward fertilization technology is the most prominent. The concept and practice of "exchanging large inputs for large outputs" has brought about three serious problems: First, because the potato itself has a certain limit to the absorption of nutrients, the excess fertilizer is lost with surface runoff, resulting in Serious environmental pollution, and this pollution has a tendency to accumulate and increase year by year; second, due to excessive fertilization, especially the imbalance of N, P, and K fertilizers, which seriously damages the repair and maintenance capabilities of the soil itself; third, to maintain relative For high yield, farmers must increase the amount and type of fertilization year by year, and due to the lack of balanced fertilization technology, the yield has not increased synchronously with the increase in fertilizer, which has increased the investment in potato planting, especially in the year of fertilizer price increase, potato planting has obvious benefits decline

Therefore, it is of great significance to the development of the potato industry to carry out scientific research on high-yield, high-efficiency, and balanced fertilization technology for potatoes, and to establish a guiding system of cost-effective and efficient fertilization technology for potatoes. Improper digging can easily cause damage to the surface of potatoes, causing potatoes to rot when exposed to air, or being rotted by microorganisms in the soil, resulting in quality decline or even toxicity, which greatly affects the taste and edible value of potatoes

The main problems are as follows: (1) Potatoes are planted for a long time in the planting area, resulting in a decrease in yield; (2) Repeated topdressing during the planting process increases labor costs, and most of the chemical fertilizers are chemical fertilizers, which easily cause soil compaction or salt Alkalization; (3) When harvesting potatoes, it needs to consume more labor, and soil compaction makes digging difficult, and may even be dug; (4) Repeated planting is not possible; the existence of the above problems leads to a decrease in potato production, which in turn results in economic benefits reduce
