Drought slope ridging cultivation method for psidium guajava

Abstract

The invention discloses a drought slope ridging cultivation method for psidium guajava. The drought slope ridging cultivation method comprises the steps: building strap-shaped slope-to-terraces with equal heights on a drought slope with a gradient of 5-25 degrees, wherein the tread of each of the strap-shaped slope-to-terraces with equal heights is 3-4m; digging a planting trench in the middle of each tread; ridging after the planting trench is backfilled by using mellow soil, wherein the ridge direction is the same as the direction of the slope-to-terraces; digging planting holes in the planting trench in a ridge according to the planting density, backfilling backfilling soil of the planting holes after being fully mixed with a base fertilizer in the planting holes so that the backfilling soil is higher than the ridge surface by 5-15cm, watering to ensure that the backfilling soil naturally sinks; and planting psidium guajava trees in the ridged planting holes. According to the drought slope ridging cultivation method, the slope-to-terraces are built in a drought slope, and the ridging and the planting are performed on the slope-to-terraces, and thus the ground temperature of a soil layer around a tree body can be promoted to be increased, and the content of water in the soil layer around the tree body can be promoted to be improved; a large number of absorbing roots can be simultaneously promoted to grow so that vertical roots are distributed shallowly and horizontal roots are distributed widely, the tree body can be promoted to absorb nutritional ingredients; the blossoming and fruiting are advanced, and the yield of fruits is favorably increased and the quality of the fruits is favorably improved.

Description

technical field [0001] The invention relates to agricultural technology, in particular to a ridge cultivation method for pearl guava on dry slopes. Background technique [0002] Pearl guava, commonly known as guava or pluck. Taiwan guava is a fruit tree of the Myrtaceae guava genus. The meat is very soft, the gravy is rich, the taste is sweet, almost seedless, and the flavor is close to that between pear and Taiwan jujube. Its fruit is oval, milky green to milky white in color, extremely beautiful, contains a lot of potassium, iron, carotene, etc., and is extremely nutritious. Guava is one of Taiwan's native fruits, and it is also a first-class weight-loss fruit with good economic value. Therefore, many subtropical regions have begun to plant it. However, subtropical hot and dry valleys have many mountains and little land, so pearl guavas are mostly planted on dry slopes. Due to the drought, lack of water and serious nutrient loss, the yield, quality and planting benefits ...

AI Technical Summary

Problems solved by technology

However, subtropical hot and dry valleys have many mountains and little land, so pearl guavas are mostly planted on dry slopes. Due to the drought, lack of water and serious nutrient loss, the yield, quality and planting benefits are not ideal, which seriously affects the development of guavas by farmers. industry enthusiasm
