Problems solved by technology

[0003] Fruit trees often have physiological diseases due to calcium deficiency, such as bitter pit of apples and black heart of pears. The occurrence of these physiological diseases seriously affects the commodity quality of fruits and reduces economic income.
Soil application of calcium fertilizer is the main method to supplement the calcium nutrition of fruit trees, but the occurrence of calcium deficiency in fruit trees is often due to the loss or fixation of calcium fertilizer, and the efficiency of calcium supplementation is low

Embodiment 1

[0033] Embodiment 1: 'Fuji' apple test

[0034] A method of calcium supplementation for fruit trees based on the integration of water and fertilizer, specific component content and implementation measures: In the spring and April, 6 cylinders with a depth of 40 cm and a diameter of 30 to 50 cm are dug down equidistantly around the apple fruit tree along the tree crown projection Shaped soil pit, wheat straw is beaten into 40cm high, 30-50cm in diameter (it is advisable to just fill the pit with wheat straw bales) Cylindrical straw bundles are put into the pit, 15g of fulvic acid, 20g of water-soluble chitosan Mix sugar and 300g of calcium ammonium nitrate thoroughly to obtain a mixture, sprinkle the mixture evenly into the gap in the middle of the wheat straw bales, and finally cover the cylindrical pit with plastic film, and needle 6 small holes (diameter 0.3-0.5cm small holes, the distance between the small holes is 5-10cm), and then align the outlet of the capillary with th...

Embodiment 2

[0038] Embodiment 2: 'Yali' test

[0039]The difference between this embodiment and Example 1 is: the fruit tree is a pear tree, the specific component content and implementation measures: in April in the spring, dig four 60cm deep and 30-50cm in diameter around the Yali fruit tree along the crown projection. In a cylindrical pit, corn stalks are beaten into a cylindrical pit with a height of 60cm and a diameter of 30-50cm (it is advisable to just fill the pit with straw bales). 250g of calcium ammonium nitrate is fully mixed to obtain a mixture, and the mixed mixture is evenly sprinkled into the gap in the middle of the corn stalk bundle, and then covered with a biodegradable mulch (such as a plant fiber mulch or a starch-filled mulch) on the top of the pit. Acupuncture 6 small holes on the film (the diameter of the small holes is 0.3-0.5cm, and the distance between the small holes is 5-10cm), and then when the small tube flows out, the outlet of the capillary is aligned with...

Abstract

The invention provides a calcium supplementation method of fruit trees based on integration of water and fertilizer and relates to the technical field of calcium supplementation for fruit trees. In the spring of March to April, 4-6 cylindrical soil pits with diameter of 30-50cm are dug under the crown projection around fruit trees; straw is bundled into a cylindrical bundle which rightly fills up a soil pit and put into the soil pit; 10-20g fulvic acid, 20-30g water soluble chitosan and 250-300g calcium ammonium nitrate are well mixed; the mixture is evenly spread in the intermediate gaps of the straw bundles and finally the soil pits are covered with mulch films on the above; multiple small holes with diameter of 0.3-0.5 cm and with intervals of 5-10 cm are pinpricked on the mulch film so that water supplement is fulfilled along the mulch film small holes by means of the tube outflow method, and the water supplement volume is 15-20L / soil pits. By means of the method, water is saved, calcium supplementation for fruit trees is fulfilled, fruit physiological disease is reduced and soil organic matter is increased.

Description

technical field [0001] The invention relates to the technical field of calcium supplementation for fruit trees, in particular to a calcium supplementation method suitable for fruit trees such as apples and pears. Background technique [0002] Calcium is one of the nutrient elements necessary for the growth and development of fruit trees. It can maintain the stability of cell walls, cell membranes and membrane-bound proteins, regulate the growth and development of trees, and act as a second messenger and calmodulin (CAM) for intracellular function regulation. ) combined to participate in the physiological and biochemical processes of fruit trees. 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 the apple tissue can reach 90% of the total calcium, and the cells are stimulated by external factors. At the s...
