Organic fertilizer special for tomato planting and preparation method thereof

Abstract

The invention discloses an organic fertilizer special for tomato planting and a preparation method thereof. The organic fertilizer comprises the following raw materials, by mass: 45-55 kg of wheat straw, 25-35 kg of tomato straw, 4-6 kg of a decomposition agent and 4-6 kg of biogas slurry sustained-release microspheres. The special organic fertilizer for tomato planting is mainly prepared from natural organic materials; no chemical fertilizer is added; therefore, the environment-friendly effect is achieved in the use process and soil and water body pollution cannot be caused; the outer part ofthe fertilizer is composed of the plant straw and the decomposition agent, the biogas slurry sustained-release microspheres are arranged inside the fertilizer, the purposes of releasing biogas slurryand continuously providing nutrition are achieved along with slow disintegration of the microspheres in soil. The fertilizer is more suitable for the growth cycle of tomatoes, labor investment of fertilization can be greatly reduced after long-term use, and the fertilizer has good economic value.

[0002] Tomatoes have a unique flavor and are rich in nutrients. They can be used as a vegetable or a fruit, and are very popular among consumers. However, most of the tomatoes currently grown contain low sugar, sour taste and poor taste

At the same time, as a large agricultural country, our country has a large demand for fertilizers, but due to the requirements of the soil environment and the nature of chemical fertilizers, the effective utilization rate is not high, resulting in serious waste and soil salinization and compaction.

[0003] my country is the country with the largest tomato cultivation area and the largest production volume in the world. Ensuring stable and increasing tomato production is the most important goal. The suitable low temperature for tomato root growth is 18-20°C, and the lowest is 13°C. When the soil temperature is too low, directly Affecting the light and efficiency and growth of tomatoes, the night temperature lower than 8.2 ℃ will reduce the root activity of tomatoes. Therefore, the low temperature at night in winter or even cloudy days is an important problem faced by tomato production, but the relevant fertilizers currently on the market Most of the focus is on nutrient supply, ignoring the root temperature

At the same time, tomatoes require less fertilizer in the early stage of growth, and the amount of fertilizer required in the peak period increases sharply. The application of ordinary fertilizers requires repeated topdressing during the tomato growth period, and the fertilizer use efficiency is reduced. Therefore, a suitable slow-release fertilizer has been developed for tomatoes. also important
