Mechanical two-step harvesting process for pineapple stems and leaves

Abstract

The invention discloses a mechanical two-step harvesting process for pineapple stems and leaves, which comprises the following steps: (a) cutting pineapple plants into upper sections and lower sections by using a rotary knife type cutting device, and harvesting the upper sections of the pineapple plants; and (b) moving the lower sections of the pineapple plants out of the soil through equipment, and harvesting the lower sections of the pineapple plants. The pineapple plants are cut through the rotary knife type cutting device, rotary knife type cutting can reduce resistance brought by pineapple stems to the cutting device, the whole pineapple plants are prevented from being taken up, and therefore a large amount of soil is prevented from being mixed on the pineapple stems and leaves. besides, the upper sections of the pineapple plants are preliminarily harvested, the upper sections comprise most of pineapple leaves, the upper sections of the pineapple plants are not mixed with soil, and excessive treatment is not needed after harvesting; and then the lower sections of the pineapple plants are harvested, the lower sections of the pineapple plants are mainly pineapple stems and a small part of pineapple leaves, even if the pineapple stems and the pineapple leaves are mixed with soil, the soil can be easily separated out, and the follow-up treatment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of pineapple stems and leaves, in particular to a mechanized two-step harvesting process for pineapple stems and leaves. Background technique [0002] After the fruit is picked during pineapple planting, a large number of pineapple stems and leaves will be left in the field. The yield of stems and leaves produced by each hectare of pineapple plantation can reach about 40 tons. The usual way is to use a crusher to smash it on the spot to make fertilizer. This treatment has two hidden dangers: one is that a large amount of organic acids are produced during the fermentation of soil organic matter, which affects the rooting of pineapple seedlings; In addition, pineapple stems and leaves are rich in nutrients, mainly including: protein, carbohydrates, fiber, starch and potassium, calcium, magnesium, phosphorus, sulfur and other nutrients and trace elements. At the same time, pineapple stems can be used to extr...
