Papaya dwarfing planting method

Abstract

The invention discloses a papaya dwarfing planting method, which comprises the following key steps of: root deepening, ridging, twisting, water control and biological control. Through the physical mandatory twisting technology, a trunk is shortened, the wind resistance is improved, the ordinary production management is facilitated, and the production period is prolonged; through twice or more twisting, the posture of the trunk is adjusted, and the center of gravity of the trunk is regressed; in the process of twisting, partial tissues and nutrient transporting pipelines in a stem rod are mechanically damaged, the trunk can be prevented from spindling, the accumulation of nutrients at the bottom is reinforced so as to crosswise thicken and enlarge the stem rod of a papaya fruit tree, and the pitch between leaves is obviously shortened; and through the application of biological active substances and microbial agents, the growth environment of a papaya root system can be improved, the robust growth of the root system is promoted, and the purposes of dwarfing, compact planting, rod strengthening and high yield are effectively achieved.

Description

technical field [0001] The invention relates to a method for dwarf planting of papaya, which belongs to the technical field of agricultural production. Background technique [0002] Papaya (scientific name: Carica papaya) is mainly planted in Fujian, Guangdong, Guangxi, Hainan and other southern regions of China. The fruit is sweet, delicious and nutritious. It is one of the four famous fruits in Lingnan. The planting area in our country is increasing year by year, and the market has great potential for development. [0003] Although the papaya fruit tree grows fast and has a high fruit-bearing capacity, as a shallow-rooted herbaceous plant, it has several inherent disadvantages: first, the tree stem is hollow, top-heavy and easy to break after a large amount of fruit bearing, and has poor lodging resistance; The root system is shallow and the tree is heavy, which is easy to fall and cause root damage and rotten roots; the third is that during the growth period, when the wa...

[0003] Although the papaya fruit tree grows fast and has a high fruit-bearing capacity, as a shallow-rooted herbaceous plant, it has several inherent disadvantages: first, the tree stem is hollow, top-heavy and easy to break after a large amount of fruit bearing, and has poor lodging resistance; The root system is shallow and the tree is heavy, which is easy to fall and cause root damage and rotten roots; the third is that during the growth period, when the water and fertilizer are sufficient, it is easy to cause leggy growth, and the tree trunk that is too high is easy to be blown down by the wind, and it is not conducive to production management such as spraying and picking. basically lost its commercial value

The method generally adopted now is to completely replace and replant after two years of fruit picking, which will result in high cost investment and short fruit picking cycle, which reduces the economic benefits of papaya planting.

In order to prevent papaya trees from lodging, many places adopt the support method of erecting frames. Although the problem of lodging is basically solved in this way, it is laborious and laborious, which increases the production cost; there are also some that use mandatory bending to reduce the height of fruit trees. effect, but its disadvantages are also very obvious. First, the papaya tree stem is brittle, and the tree stem is easy to break if the mandatory bending force is slightly larger, and the effect of lowering the height of the fruit tree cannot be achieved if the force is small; the second is the center of gravity of the fruit tree after bending Offset, the greater the degree of bending, the more the center of gravity will shift. In addition, the roots of the tree are shallow, and the roots are easy to be pulled and broken, causing diseases such as root rot and stems. In severe cases, the fruit tree will fall and break

In addition, some chemical agents such as paclobutrazol, chlormequat, etc. are used to regulate plant growth and dwarf plants, but there are still problems such as drug residues and are not allowed to be used in organic planting.
