Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of planting fertilization technical field, specifically a kind of peanut planting fertilization device BACKGROUND

[0002] Peanut has higher nutritional value, contains rich protein and fat, especially the content of unsaturated fatty acid is very high.In addition, it also contains a large amount of vitamin E, vitamin B group, mineral nutrients and other nutrients.Therefore, peanut is praised as "plant meat" by people.

[0003] The best planting time of peanut is usually in mid-April to early May, that is, before and after the time of Gu Yu.This is because peanut is a warm crop, and its suitable temperature for growth is above 12℃.The yield and quality of peanut planting are affected by many factors, among which fertilization is a key factor.In general, the fertilization of peanut should be divided into two stages of base fertilizer and topdressing.Base fertilizer is usually applied before sowing, accounting for more than 80% of the total amount of fertilization, mainly using organic fertilizer, combined with nitrogen, phosphorus and other fertilizers.Topdressing is carried out at seedling stage and after flowering, mainly to provide key nutrients for crop growth.

[0004] In peanut planting, there are two ways of fertilization, one is direct spreading of fertilizer, and the other is trench fertilization.Direct spreading of fertilizer is simple, and the fertilizer is directly and evenly spread on the soil, and then the surface layer of fertilizer is gently poked to mix with the soil.Trench fertilization needs to dig a trench in front of or on the row of peanut planting first, then put the fertilizer evenly in the trench, and then bury the fertilizer with soil.

[0005] Trench fertilization can better mix fertilizer with soil, so that it is more fully absorbed and utilized by plants, and the fertilization effect is better, while direct spreading of fertilizer is convenient, but the mixture of fertilizer and soil is not sufficient, and the fertilizer supply for peanut is relatively poor.Trench fertilization can make full use of fertilizer, so it saves a part of fertilizer relatively, while direct spreading of fertilizer is easy to cause excessive application and waste of fertilizer.

[0006] Most of the existing trench fertilization devices are not equipped with timely watering irrigation structure after fertilization to help fertilizer dissolution and absorption, and most of the devices are not equipped with quantitative fertilization structure, which cannot accurately control the amount of each fertilization according to the growth cycle of peanut, and manual fertilization leads to difficulty in controlling fertilizer amount.
