Planting techniques and yield per mu of papaya

Papaya belongs to the rose family fruit, the plant is a small tree. Mainly produced in Shandong, Shaanxi, Henan, Hubei, Jiangsu, Guangxi and other temperate and subtropical, tropical areas. How should papaya be planted, what kind of growing environment is needed, and how should we manage the growth of plants after planting? And how much yield does one acre of papaya produce? Is it proportional to investment? Therefore, the following mainly introduces the issues that everyone is concerned about.

I. Yield per mu

Papaya planting, if it meets the growth requirements, proper management, suitable climate, under normal circumstances planting one mu of papaya yield, about 60 to 100 jin per tree. And then there's about 120 to 150 trees per acre. The yield is about 7200 to 15000 jin. However, it was only a rough figure for reference. After all, the density of sloping land and flat land was different, and the yield of each tree was not absolute.

II. Cultivation techniques

1. planting density

Papaya is generally planted in spring, winter temperature higher can also be planted in autumn, winter cold places can be planted in autumn, but more than one winter management, more than worth the loss. Generally, the sloping fields planted are different from the flat fields. The sloping fields are sparsely planted and the sloping fields are densely planted. Common suitable spacing is flat row spacing 3 meters, spacing 4 meters, slope row spacing 2 meters spacing 3 meters.

2. Fertilization and water control

Papaya planting should be heavy 2 fertilizer base fertilizer, base fertilizer application amount accounts for more than 60% of the annual fertilizer amount, so as to ensure soil fertility, as well as continuous supply of nutrients, can meet the long-term fertilizer needs. After applying base fertilizer, irrigate once to dilute fertilizer and dissolve it into soil. Later to the flowering period and then two topdressing can be. Once before flowering, once bearing fruit. Water after fertilization, or dissolve directly in water for application.

3. bear fruit

Topdressing once before flowering, using quick-acting fertilizer can promote flower bud differentiation, and applying farm manure can continuously supply nutrients throughout flowering. Flowering does not fertilize, flowering can collect pollen, artificial pollination, ensure pollination fertilization. Or bees to pollinate. Some flowers are incomplete and redundant, and they should be thinned in time. After the results can be sprayed fruit preservation agent fruit preservation.

4. plant adjustment

Papaya plants are usually cylindrical and spindly. This is convenient for management, so after planting and growing, it is necessary to set the stem and cultivate the branches. gradually growing into trees. After molding, only dense branches, weak branches, redundant branches, diseased branches, excessive branches and the like need to be pruned. Reducing unnecessary nutrient consumption is enough.

Papaya planting methods, there are certain stresses, planting methods and management, growth conditions, determine the final planting yield, or there are certain influencing factors.
