Field management method of pistachio

Pistachio, a tropical fruit native to America, has also been supplied in the market in recent years. To people's love, because of the shape of a human heart to get celebrity pistachios. High nutritional value began to be cultivated, but some friends also want to grow their own, suffering from lack of experience, then today I will briefly introduce some of what I know to you.

1. Soil

Soil requires that the structural layer is sound, and the tillage layer and infiltration layer can not be broken. Generally speaking, it is necessary to have fertile and loose deep soil, if the conditions are limited, the soil can be improved, mainly by applying rotten fertilizer to improve barren, middle ploughing to improve consolidation, trenching and ridging drainage to solve stagnant water, sand can be mixed to improve permeability. So that the soil can be cultivated.

Second, water control

Like the humid environment, need the environmental humidity can be higher than other fruit trees, but not stagnant water, water stains the root system, with growth risk, will rot the root, stop growing and die. Watering requires the most watering in the flowering and fruiting stage, and can be kept moist for a few times when the long leaves grow normally in the early stage. Do not water the fruit after changing color to avoid too much moisture. A large amount of flood irrigation is needed to replenish the consumption after harvest.

III. Fertilization

New shoots need a lot of nutrients in spring, and some available nitrogen fertilizer can be applied to make the shoots grow rapidly. Promote more new shoots and increase the crown. Adult trees that can bear fruit can apply shoot-promoting fertilizer in three years. When it comes to the fruiting period, you can apply more phosphorus and potassium fertilizer, or farm manure, plant ash, and so on, to provide nutrients for the whole fruiting period.

To ensure the nutrition of the fruit. Fertilizing and replenishing tree nutrition after harvest can apply half of the base fertilizer in the coming year, which can also be regarded as a kind of base fertilizer. Fertilization can increase the temperature and survive the winter.

4. Temperature and light

Pistachios like a high temperature environment, with a suitable temperature of 22 to 30 degrees Celsius and a low temperature of 2 to 3 degrees in winter. big trees will suffer at a low temperature of minus 2.2 degrees Celsius, severe freezing damage will occur within a few hours at minus 4.5 degrees Celsius, and seedlings will be killed by freezing at minus 1 degrees Celsius. Can not accept strong sunlight, generally need to cover the sunshade net planting, otherwise easy to drop flowers and fruits, cloudy days can take off the sunshade net.

At present, the experience of planting pistachios is not as good as that of other fruit trees. But some basic needs will have something in common. Therefore, generally speaking, as long as we do the demand adjustment work needed for the growth of the above fruit trees according to the characteristics. It should be able to ensure good growth.
