Background
Chinese torreya is distributed in the south area of Yangtze river in China, belongs to evergreen plants of Chinese torreya of Taxaceae, is a rare economic tree species in the world, has special high-grade nuts in China as fruits, has high nutritional value, and has health care and medicinal values and comprehensive development and utilization values. The torreya grandis kernels are fried and eaten, are crispy and delicious and are top-quality dried fruits with rich nutrition. The torreya grandis nut has the effects of moistening skin and delaying aging, is rich in components beneficial to eyes such as vitamin A and the like, and has the effects of preventing and relieving symptoms such as dry eyes, nyctalopia and the like.
The growth period of Chinese torreya is long, the growth of seedlings is slow, and the success rate is low. The roots of the Chinese torreya are fleshy roots, the reaction to fertilizer components is strong, and the selection of the organic fertilizer with lasting fertilizer efficiency is more beneficial to the growth of Chinese torreya plants. The Chinese torreya seedlings grow well in deep fertile, loose and well-drained soil, so that reasonable fertilization is an important guarantee for the rapid growth of the Chinese torreya seedlings.
In the traditional Chinese torreya production, a single fertilizer, such as urea of a nitrogen fertilizer or nitrogen-phosphorus compound diammonium phosphate, is applied all the year round, so that the yield of the Chinese torreya is low, the quality of the Chinese torreya is poor, the utilization rate of the fertilizer is low, the production cost is improved, and the economic benefit of farmers for planting the Chinese torreya is not ideal.
In the production of the compound fertilizer, the nutrient condition of soil is measured by using a soil testing formula, and the application amount, the application period and the application method of fertilizers such as nitrogen, phosphorus, potassium, medium and trace elements are provided on the basis of soil testing and fertilizer field experiments according to the fertilizer requirement rule of crops, the fertilizer supply performance of soil and the fertilizer effect on the basis of reasonable application of the organic fertilizers. Generally speaking, the formulated fertilizer is applied under the guidance of agricultural science and technology personnel, the core of the soil testing formulated fertilizer application technology is to adjust and solve the contradiction between the fertilizer requirement of crops and the fertilizer supply of soil, and meanwhile, the nutrient elements required by the crops are supplemented in a targeted manner, and what elements are needed by the crops when the crops lack the nutrient elements, so that the balanced supply of various nutrients is realized, and the requirements of the crops are met; the purposes of improving the utilization rate of the fertilizer, reducing the using amount, improving the crop yield, improving the quality of agricultural products, saving labor and saving expenses and increasing income are achieved.
However, the existing fertilizers for Chinese torreya planting have the problems of weak pertinence, low utilization rate and non-ideal economic benefit, so that special fertilizer for Chinese torreya and related production process matched with the fertilizers are urgently needed in Chinese torreya production so as to maintain the sustainable production of the Chinese torreya industry.
