A kind of fast persimmon gardening method

Abstract

The invention discloses a method for quickly growing a persimmon garden, which comprises the steps of: (1) selecting a rootstock and soaking the seeds of C. chinensis in a mixed solution of KNO3+10mol·L-1 sodium nitroprusside (SNP) with a mass volume ratio of 0.1% for 24 hours; (2) Seedling cultivation in nutrient pots, the substrate formula is peat: vermiculite: garden soil = 1: 1: 1, and the formula is added with 0.02% potassium permanganate (KMnO4) according to the mass ratio; (3) Garden planning and soil improvement; (4) Rootstocks are directly planted to build gardens and management, and are directly transplanted to build gardens in early April; (5) Grafting time and method, the improved median splitting method is adopted in early and mid-June; (6) Management of grafted seedlings in gardens, grafting After 10 days, apply 3% gibberellin (GA4+7) ointment on the buds. The seedling survival rate of the invention is 9.62% higher than that of the conventional gardening method, the root system is developed, the young trees grow stronger in the next year, and the gardening cost per 667m2 is 42.59% lower than that of the conventional gardening.

Description

technical field [0001] The invention relates to the field of fruit tree cultivation, in particular to a method for quickly building a persimmon "three-dang" orchard, that is, rootstocks are sown and seedling-raised in the same year, planted in the same year, and the garden is grafted in the same year. Background technique [0002] China is one of the main countries of origin of persimmon. Its output and area both rank first in the world. In particular, Shaanxi, Shanxi, Henan, Hebei, and Shandong in the Yellow River Basin are the most cultivated. This year, the persimmon industry in Guangxi, Fujian, Anhui, Guangdong, and Yunnan has developed rapidly, especially sweet persimmon, which is a special economic crop. Persimmon is also one of the most distinctive economic crops in mountainous areas of our country. It is easy to manage, easy to produce high yields, and has high economic benefits. It is widely cultivated as a courtyard in mountainous areas and has become a pillar indu...

Problems solved by technology

The root system of the seedlings grown for 2 years in the nursery is strong and widely distributed. During the process of seedling raising, transportation and planting, the roots are easy to be damaged. Low, especially when building gardens in mountainous areas and hills, due to the poor site conditions for building gardens, many places cannot be irrigated, resulting in poor gardening efficiency

In the newly built persimmon gardens in some mountainous areas of Hubei Province, the survival rate of seedlings is often less than 70%, and the growth of seedlings is poor, the emergence of new shoots is slow, and the initial production period is delayed to 5 years later, which seriously affects the enthusiasm of fruit farmers.

[0004] Aiming at the technical problems of the existing persimmon gardening process, such as long slow seedling period, low survival rate, and long gardening management cycle, how to create a method for rapid persimmon gardening, sowing seedlings, planting, and grafting in the same year. garden, an urgent problem to be solved for the sustainable and healthy development of my country's persimmon industry
