Embodiment 1

[0040] Embodiment 1 prepares water retention matrix

[0041](1) The production of decomposed macadamia nut exocarp: crush the mature fresh macadamia nut exocarp into particles with a particle diameter of less than 1cm, and then ferment in the open air for 30 days according to the ratio of 1 cubic macadamia nut exocarp + 1 kg of urea. Turn over and ventilate once every 2 days; get decomposed macadamia nut exocarp;

[0042] (2) 3 parts of macadamia exocarp that above-mentioned steps (1) obtains are mixed with 1 part of vermiculite, 1 part of perlite;

[0043] (3) Mix the result of step (2) with 100g polyacrylamide, 200g polyacrylamide, 300g polyacrylamide, 400g polyacrylamide and 500g polyacrylamide respectively to obtain different water-retaining substrates 1-5.

Embodiment 2

[0044] Embodiment 2 fertilizes macadamia nut trees and compares effects (fruit trees in high yield period)

[0045] Overview of the implementation site: in the macadamia test base of the Yunnan Institute of Tropical Crops Science, Jingha Township, Jinghong City, Yunnan Province. The test site is located at 22.05° north latitude and 100.80° east longitude. The two-year average temperature of the place is 22.4°C, the average annual evaporation is 1386.2mm, the accumulated temperature ≥ 10°C is 8114.3°C, the annual rainfall is 1185.8mm, and the altitude is 820m. The slope aspect of the implementation site is southwest Slope, slope 6°-15°, red soil, pH 4.58, medium fertility.

[0046] The planting varieties include: O.C, HEAS344, HEAS294, HEAS788, HEAS246, HEAS800, HEAS 695 and other 16 varieties, among which O.C and HEAS344 account for a relatively large proportion of planting, both of which are above 15%.

[0047] The variety HAES344 is selected as the object of implementation,...

Embodiment 3

[0066] Embodiment 3 fertilizes macadamia nut trees and compares effects (primary fruit trees)

[0067] Implementation location: The macadamia planting base of Yunxian Zhengcheng Agricultural Development Co., Ltd. is located in the balsa forest group of Maojia Village Community, Aihua Town, Yunxian County, Lincang City, Yunnan Province, at 24°27′25″ north latitude and 100°09′36″ east longitude. The planting altitude is 1300m~1350m, and the planting area of ​​macadamia nuts is 180 mu. It was planted in 2011, among which O.C and HEAS344 were planted for 6-7 years, A4, A16 and Guire 1 were planted for 4-5 years, and other varieties include HEAS294 and HEAS 695 etc.

[0068] Select HEAS344 as the implementation object, the tree is 6 years old, the plants have not been closed, and the planting density is 4.0 m×7.0 m.

[0069] Operation method: This method was adopted on March 20, 2018; 10 trees were selected as observation trees, and the specific fertilization methods were as follo...

Abstract

The invention discloses a drought-resisting fertilizing method for macadimia nuts in the mountainous region. The method comprises specific processes as follows: covering the land with decomposed matter, digging a fertilizing pit, performing filling, applying fertilizer with a sandwich technique and expanding the fertilizing pit at the right time. According to the fertilizing method, the water andfertilizer utilization effect of a macadimia nut orchard is remarkably improved, the problems that the fruit setting rate is limited and the fertilizer utilization rate is not high due to seasonal drought of the macadimia nut orchard in the mountainous region at present are solved, and therefore, the economic benefit of the macadimia nuts in the mountainous region is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilization, more specifically to a drought-resistant fertilization method for mountain macadamia nuts. Background technique [0002] Macadamia is an evergreen arbor tree belonging to the family Saccharidae. In recent years, macadamia has developed rapidly in China. Statistics show that in 2017, the planting area of ​​macadamia in China was 2.7964 million mu, of which the planting area in Yunnan was 2.6098 million mu, accounting for the national total. 93.32% of the area; in Yunnan, macadamia nut planting areas are dominated by mountainous (including hills) landform types, and macadamia nuts are basically planted in mountainous areas, forming a characteristic mountainous planting model. The average rainfall in the mountainous planting areas of this area is above 1000 mm, but the distribution is uneven in time and space. In terms of time, the drought is severe in winter and spring. true por...
