Fertilization technology of fig tree

In recent years, rising production figs, figs raise health value of its high camp, get the favor of consumers, many farmers have played a kind of fig tree, but many farmers ignored the fig tree management, resulting in figs yield, quality The decline has caused no small losses, and the fertilization technology of figs is now discussed with the majority of farmers.

　　 1 . Fertilization period, base fertilizer and top dressing

　　 (1) basal basal figs administration period can be trimmed at the end of 11 to 12 months, but in late February to early March administration is appropriate. The fig is not ploughed like other fruit trees. The fertilizer is applied early and spread on the surface of the dead leaves, which will be lost with wind and rain and snow. But it should not be applied too late. After March , the application of base fertilizer, fertilizer decomposing, decomposition and infiltration will take some time, and the early absorption and utilization of plants will be affected. The base fertilizer is mainly organic fertilizer, and combined with compound fertilizer. It can supply nutrients needed for plants for a long period of time, continuously replenish nutrients and restore tree potential. Material conditions are also prepared for the leap year growth results.

    ( 2 ) The application period of topdressing and topdressing of figs is divided into pre-fertilization (summer fertilizer) and late topdressing (autumn fertilizer) in fig cultivation. That is the foundation on the basis of Fertilizers on the fertilizer requirement characteristics of each period for supplies fertilizer to adjust the tree to mention the growth and results of contradiction, to ensure high yield and quality.

    The specific period and number of top dressings should be based on plant growth and soil fertility. It is usually carried out in 3 to 6 times. In high temperature and rainy areas, nutrients are easy to lose, the number of topdressing should be more, the amount of fertilizer should be less; the tree is weak, the roots are poorly grown , and the number of top dressings must be increased; the young trees have to master the early application and early application of topdressing, and later apply less, thus promoting new The growth of the shoots is enhanced and the cold resistance is enhanced.

    Fig plants have a large amount of growth in the early stage and require more fertilizer. With the new shoots continuously carried inflorescence differentiation, in late May to mid-July peak of fertilizer requirement, this time dressing plays a key role throughout the growing season. It mainly solves the contradiction between nutrient supply and demand during the elongation of new shoots, fruit development and nutrient storage during tree storage.

    2 . The amount of fertilized fertilized amount of fertilization must be comprehensively analyzed by soil fertility, tree age and yield target. And through the fertilization test, the production practice continues to adjust, so that the amount of fertilizer can better meet the needs of fig growth .

    The soil is fertile, the organic matter is more, and the tree is strong. The amount of fertilizer applied is 10%~15% less than the standard amount . Plants with strong trees in the same garden are less applied; weak trees should be applied more appropriately to meet nutrient supply and promote strong trees. But one can not fertilize too much, at times as far as possible, to prevent the emergence of high concentrations of fertilizer root fertilizer damage. The amount of fertilizer applied to young trees is generally 60% to 70% of that of adult trees . Saplings of excessive fertilization, prone to shoot not only full length, germination many invalid Fushao, cold tolerance decreased, resulting in winter frost damage. It should be avoided to increase the rate of fertilization to speed up the process of entering the park, but the speed is not up, which often leads to failure.
