Foliar fertilizer special for pineapples and application method thereof

Abstract

The invention provides a foliar fertilizer special for pineapples and an application method thereof. The foliar fertilizer special for pineapples is prepared from the following effective elements metered by pure nutrient in percentage by parts: 20-40 parts of nitrogen, 3-40 parts of phosphorus pentoxide, 12-42 parts of potassium oxide, 4-12 parts of magnesium oxide, 2-10 parts of ferrous iron, 0.1-0.4 part of zinc and 0.1-0.4 part of boron. The foliar fertilizer special for pineapples is applied in the mode of leaf surface spraying or micro-belt spray irrigation and can obviously solve the problems of trace element deficiency and nutrient imbalance of the pineapples, promote the growth and the development of the pineapples and improve the output and the quality, wherein the output of the pineapples is improved by 16.0 percent, the fruit commodity rate is improved by 11.8 percent, and the content of soluble solid is improved by 7.9 percent. The foliar fertilizer special for pineapples is simple and convenient to prepare and apply, has low price and is beneficial to large-scale popularization and application.

Description

technical field [0001] The invention relates to fertilizer technology, in particular to a special foliar fertilizer technology for pineapple. Background technique [0002] Pineapple (Ananas comosus (L.) Merr) is native to tropical America and is the third and seventh largest tropical fruit in the world. my country's pineapple cultivation originated in the middle of the 16th century. Now my country has become the fourth largest pineapple producer in the world and occupies an important position in the world's pineapple production and trade. The pineapple industry is also becoming an important industry in my country's tropical and subtropical regions. Farmer income plays an important role. [0003] my country's pineapple is mainly planted in Leizhou Peninsula in Guangdong, Wanning in Hainan, Qionghai, Changjiang, southeastern Guangxi, Xishuangbanna in Yunnan, Dehong, Longhai in Fujian, Zhangpu and other hilly slopes (slope between 0°-35°). The soil texture of pineapple gardens...

AI Technical Summary

Problems solved by technology

Because the calcium superphosphate in the foliar fertilizer contains too much free acid, it is easy to burn the pineapple leaves, thereby affecting its growth; and the proportion of nitrogen in these foliar fertilizers is too high, and the proportion of potassium is too low, causing the pineapple to flourish and the leaves to grow. Too long, with narrow leaves and small stems, which eventually lead to low fruit weight, which reduces pineapple yield

In addition, pineapple garden soil is prone to lack of medium and trace elements, such as magnesium, iron, zinc, boron, etc., especially the lack of soluble ferrous and replaceable magnesium in the soil will cause iron and magnesium deficiency in pineapple plants, and the lack of iron and magnesium will reduce Increased the chlorophyll content of pineapple leaves, thereby reducing the production of pineapple photosynthetic products, affecting pineapple growth and pineapple yield

However, the foliar fertilizer prepared by fruit growers hardly contains iron, zinc, and boron nutrients, and the content of magnesium nutrients is also low, which cannot meet the needs of pineapple growth and development.
