Method for quickly cultivating mulberries of Strong Mulberry Number 1

Abstract

The invention relates to a method for quickly cultivating mulberries of Strong Mulberry Number 1. The method includes fertilizing after mulberry seedlings are planted; in spring of the first year, pruning at positions being 20cm away from the ground after field planting; in early May, performing bud thinning, namely selecting and remaining 2-3 strong buds which healthy and strong in growing of upper portions and uniform in insertion position for each plant and cultivating the buds on each plant to be 2-3 branches; in early July, pinching at positions being 45cm away from the ground, cultivating to be first sub-branches, and taking pruned green leaves as leaves for summer silkworms of five years old; in early August, performing bud thinning, retaining 4-6 branches for each plant, and cultivating to be second sub-branches; in late November, performing forced top clipping; in spring of the second year, without performing spring pruning, performing summer pruning and fist determining at positions being 65cm away from the ground until the late May, retaining 3-5 fists for each plant, and cultivating to be tree shapes. By the method, the mulberries are exuberant in growing and high in annul leaf yield when fertilizer-water management conditions are good, and can be quickly cultivated within two years; the method is reliable in technology, the objective of early production and early harvesting of silkworm raisers can be achieved, and leaves obtained by summer pruning can be used as leaves for spring silkworms, so that utilization rate of mulberry leaves is increased, and income of the silkworm raisers is increased.

Description

Technical field: [0001] The invention relates to the field of mulberry planting, and more specifically relates to a method for rapidly growing Qiangsang No. 1 mulberry. Background technique: [0002] Usually, it takes 3 years for mulberry seedlings to be planted into forests and put into production. Faced with the unpredictable market conditions of cocoon silk, the price of silkworm cocoons changes every year, and the price fluctuation range is also relatively large. When the market is good, silkworm farmers are more enthusiastic about planting mulberry. But three years later when the mulberry trees become forests and put into production, the price of silkworm cocoons may have dropped, and the income of silkworm farmers will decrease accordingly. If the improvement of technology shortens the time for mulberry forests to be put into production and produces one year in advance, it will not only make early income for silkworm farmers, but also win a good market opportunity and ...

[0002] Usually, it takes 3 years for mulberry seedlings to grow into forests and put into production. Faced with the unpredictable market situation of cocoon silk, the price of silkworm cocoons changes every year, and the price fluctuation range is also relatively large. When the market is good, silkworm farmers are more enthusiastic about planting mulberry. However, the price of cocoons may have dropped when the mulberry forests are put into production three years later, and the income of silkworm farmers will decrease accordingly
