Seedling cultivating method

Abstract

The invention provides a seedling cultivating method. The seedling cultivating method is used for cultivation according to periods and seasons, and different nutrients are applied. According to the method, in accordance with different seasons, waste of different oil crops is used for cultivating and charging the seedlings, stalks of the oil crops, bark of oil crop fruits, shrunken grains, oil meal and the like are crushed and then fermented, so that the nutrients for cultivating the seedlings are made for providing fat fertilizers and fiber fertilizers for newly-transplanted seedlings, seedlings suffering from grievous injury such as hypoxia and water shortage, and providing sufficient nutrients for the roots, the branches and the leaves of the seedlings to promote root systems to develop. The seedling cultivating method disclosed by the invention has obvious repair and growth promotion effects on the young seedlings suffering from grievous injury. Besides, the nutrients can also promote the seedlings to well absorb various trace elements in soil, so that the purpose of increasing the growth speed is achieved.

However, according to the applicant’s visit to a certain place, although the number of tree plantings in my country is astonishing every year, and the seedlings account for about 40% of the total tree planting, the survival rate of the seedlings is not ideal, and the survival rate in some areas is even less than 20%.

[0003] After investigating the vegetation growth in the hilly areas in the middle and lower reaches of the Yangtze River, the applicant concluded that the reasons for the low survival rate of tree planting are as follows: First, the surface soil layer in the hilly area is dominated by red-yellow soil, white-yellow soil and black-yellow soil. The pH and trace elements contained in the seedlings are obviously different. Due to insufficient understanding of the soil where the seedlings are planted, there is a lack or serious lack of various trace elements in the soil, such as phosphorus, potassium, iron, zinc, boron, etc. low rate

[0004] The second is that there are more than 40 days of severe weather in hilly areas every year. If there is a drought, the rain cannot be supplied normally, which will easily lead to the death of seedlings.

Poor management of seedlings before planting is also an important reason for reducing the survival rate. For example, bundled seedlings are piled up in narrow seedling sheds for a long time, lacking oxygen and water for a long time, causing many seedlings to be seriously injured and half dead.

[0005] The third is that the artificial management of seedlings after planting is not perfect, such as drainage, weeding, soil loosening, and pest control, etc. Management work has not been done. At the same time, due to the long-term use of chemical fertilizers, pesticides and herbicides, the soil has also suffered to varying degrees. Pollution
