Planting technology for interplanting potatoes and sweet potatoes among young macadamia nuts in subtropical zone

Abstract

The invention provides a planting technology for interplanting potatoes and sweet potatoes in young macadamia nuts in a subtropical zone. The planting technology aims at solving the technical problems that in the prior art, the economic benefit is not high in the young macadamia nut planting period, the planting enthusiasm of fruit farmers is affected, and the problem that growth and fruiting of adult fruit trees are affected due to serious water and fertilizer loss of the young macadamia nut inter-species slope in the prior art. Winter planting and spring planting solanaceae crops are interplanted among the young macadamia nuts, specifically, the potatoes are interplanted mainly, the sweet potatoes are interplanted secondarily, the macadamia nuts are deep-rooted tree species, the potatoes and the sweet potatoes are shallow-rooted crops, space and time distribution of the macadamia nuts, the potatoes and the sweet potatoes in soil is reasonable, competition of the nuts, the potatoes and the sweet potatoes for water and fertilizer is avoided, the overall ecological benefit of an orchard is improved, the ecological environment of the orchard is improved, the economic added value and multiple cropping index of land are increased, the economic pressure of the fruit farmers is relieved, the potato harvesting and marketing time can be further flexibly adjusted, and seasonal price decline of the potatoes is avoided.

Description

technical field [0001] The invention relates to the field of planting, in particular to the planting technology of young macadamia interplanting potatoes and sweet potatoes in subtropical regions. Background technique [0002] Macadamia nuts, also known as macadamia nuts, have a unique fragrance and rich nutrition. They are known as the "Queen of Dried Fruits" and are known as the best edible nuts in the world. They have become an emerging fruit tree with rich nutritional value and high commodity value. One, the market demand is huge and the development prospect is broad. Macadamia is a perennial economic crop. It takes a long time from planting to production. During this period, there is only input but no output, and the economic burden of fruit farmers is heavy. In addition, macadamia grows slowly in the early stage, the leaf area coefficient is small, and the light energy utilization rate is not high. Long-term no vegetation coverage under wide row spacing can easily cau...
