Embodiment Construction

[0010] Calcium nitrate (1), sucrose (2) and glutamic acid (3) are mixed evenly (4) according to the weight ratio, and each component is a commercially available qualified product. Select the paper-plastic material according to the required specifications, and punch holes according to the design requirements on the punching machine (6), assemble the mixed fertilizer and the punched paper-plastic material into the packaging machine (7), adjust the length of the paper, and pack Serve (8), and the finished product is stored in a dry place.

[0011] Before the fruit tree sprouts, dig a 20 cm deep annular ditch 30 cm away from the main trunk of the fruit tree, and put 3-5 bags of calcium fertilizer in the ditch at an average distance according to the size of the tree. Tests have proved that the method for calcium supplementation for fruit trees saves labor, is safe and has good effect, and obviously improves the yield and quality of fruits.

Abstract

This invention discloses a laborsaving, safe and effective method for supplementing calcium for fruit trees. The method mixes calcium fertilizer with natural nutritious substances that can stimulate calcium absorption by fruit trees, and adopts fertilizer bag controlled-release technology to produce calcium fertilizer. The method comprises: uniformly mixing calcium nitrate, saccharose and glutamic acid at a weight ratio of 97:2:1, and packaging into bags. Each fertilizer bag is prepared from 50 g paper and 20 g polyethylene by pouring, processing into 90X160 mm, and needling 5 column micropores with 0.6 mm interspace for controlled release by a needle with a diameter of 0.25 mm. Saccharose and glutamic acid can accelerate calcium absorption by roots. The fertilizer bag controlled-release technology can ensure the application of the calcium fertilizer into roots without ruining the roots, and reduce the fixation of calcium in soil, thus can obviously increase calcium utility, prevent fruit tree bitter pit, and improve the storage performance of fruits.

Description

(1) Technical field [0001] The invention relates to a calcium fertilizer for fruit trees. (2) Background technology [0002] Calcium is an essential nutrient element for the growth and development of fruit trees. It plays an important role in participating in cell composition, regulating tree growth and development, and its physiological and biochemical processes. Calcium combines with pectin to form calcium pectate, which maintains the structure and function of the cell wall and makes the fruit have a certain mechanical strength. The calcium component combined with the cell wall in apple tissue can reach up to 90% of the total calcium; calcium can protect the cell membrane The structure and function of calcium can reduce membrane permeability and inhibit membrane lipid peroxidation, which is an important factor to delay fruit aging; calcium interacts with auxin to affect the growth and development of root tip and shoot tip meristem, and the cell division of fruit; calcium ...
