The Latest Technical Methods for Pistachio Orchard Management
The pistachio is a very famous nut with a very delicious taste, loved by many people. In fact, pistachios need to be planted in large quantities by humans; the pistachio is actually the kernel of a tree called the pistachio tree (Pistacia vera). Pistachios can not only be processed into kernels, but are now also used in various fields such as food and medicine. It is a fruit tree with relatively high planting returns, so how should we manage it when planting? Let's take a look below!
1. Fertilizer and Water Management
Pistachios require a relatively large amount of fertilizer, and a base fertilizer needs to be applied once a year, with the fertilizer amount appropriately controlled according to the number of fruit trees. The number of top dressings each year must not be less than three. The first water-and-fertilizer application is in early spring, with nitrogen fertilizer as the main fertilizer, in order to promote tree growth and improve nutrient absorption. Then, during the fruit expansion period, nitrogen-potassium fertilizer is applied. The last application is after harvest, because most of the tree's nutrients are concentrated in the fruit. After the fruit is harvested, nutrients are seriously lacking, so at this time the tree's nutrients must be replenished, mainly with farmyard manure, carried out together with deep plowing.
2. Shaping and Pruning
The pistachio is a fruit tree with a relatively high light requirement. During the planting process, appropriate shaping and pruning should be carried out according to tree vigor and tree shape. According to the degree of light requirement and the growth stage, all branches such as overly dense branches, water sprouts, and weak-growing branches should be pruned away. This can not only reduce nutrient consumption but also enhance the permeability between fruit trees. During shaping and pruning, thinning cuts should be used more often, reducing the method of directly cutting off branches. When new shoots grow to about 55 cm, the new shoots should be pinched in time to promote the growth of secondary shoots and increase the number of bearing branches.
3. Cultivation and Weeding
Cultivation and weeding is a necessary task in the process of planting pistachios. Each year, according to the soil and weed growth conditions, cultivation and weeding should be carried out at least three times. The first time is roughly before the Start of Summer, because this period is a rapid growth period for weeds and also a stage when pistachio growth speeds up. Cultivation and weeding can promote root penetration and nutrient absorption. Then the second time is around the Mid-Autumn Festival, to prevent weeds from competing with the fruit trees for nutrients and water. The last time is before harvest, to level the orchard and facilitate harvesting.
4. Flower and Fruit Management
The management of a pistachio orchard is very important. When carrying out orchard management, the goal should be to strengthen tree vigor and promote flowering and fruiting, and to increase the application of organic fertilizer. The success rate of natural pollination of fruit trees is relatively low, and the fruit-setting rate is not high either, so we need to carry out artificial pollination to improve the pollination and fertilization rate and the fruit-setting rate of pistachios. Create a good environment for the pollination of fruit trees and the growth of the plants; if they are allowed to pollinate naturally, the yield cannot be controlled, which will have a certain impact on one's own economic benefits.
The above are the orchard management methods for pistachio planting. In fact, there is another very important one that we also need to pay special attention to. That is the prevention and control of pests and diseases. The prevention and control of pests and diseases has been emphasized by the editor in every article, because it truly can have a very large impact on the plants. I hope everyone will plant with this in mind, otherwise if the yield decreases, there will be no benefit at all for yourself. That is all for today's introduction. This article is for reference only.
