The latest method of planting pistachio

The pistachio, also known as Wu Feng persimmon, is a famous tropical fruit introduced from abroad. It is mainly grown in Guangzhou, Hainan and Taiwan where the climate is warmer all the year round. Pistachio has been planted in China for some time, but it is still very rare in the market, first of all, because the planting area is small, and secondly, its yield is not high. The following is the method of planting pistachios brought to you by the pro-agricultural network. Let's take a look.

1. Land selection and preparation

The choice of planting land mainly determines the survival rate of planting pistachio. Pistachio is a kind of fruit that likes light and warmth very much, so it also determines that the climate of planting land is relatively stable all year round. The second is that the planting land had better be sunny, and the land should be relatively flat, without depressions, and then hills, plains and slopes with good wind shelter and good drainage can be done. There are only two requirements for soil preparation: the first is to turn at least 25 cm deep, and the second is to flatten the soil in time. The last thing is that the base fertilizer is fully applied, mainly farm organic fertilizer.

2. Sowing method

There are many kinds of sowing methods of pistachio, such as seed sowing, grafting, cutting and striping, etc., the most primitive is seed sowing, and it is also a more popular way of sowing at the same time. Secondly, grafting sowing is also very popular, the first is the high survival rate, the second is the guarantee of quality and output, and finally, it can shorten the growth period. Therefore, the most common way we use now is the combination of seeds and grafting, first cultivate grafted seedlings, as well as heart seedlings, and then wait until everything is ready for grafting.

3. Reasonable close planting

We usually plant in April and May every spring, and we need reasonable close planting when planting, so as to ensure the yield and quality of pistachios. Under normal circumstances, 200 to 300 pistachio trees can be planted on one mu of land, during which they can be planted according to the row spacing of 1.52 meters and the plant spacing of one meter to 1.5 meters, so as to ensure the permeability between the gardens.

4. Scientific management

Management mainly includes watering, fertilization, pruning, weeding, flower and fruit thinning, and garden cleaning, in which watering, fertilization and weeding are combined, that is, they must be put in place in one step. Basically, only three fertilizers are needed a year, usually in the way of ditch fertilization. Flower thinning is carried out in the peak period of blooming, while fruit thinning is carried out when the fruit is big after the flower fade, so as to ensure the smooth progress of the work. The final work of clearing the garden is also more important, because it can prevent and cure some diseases, at the same time, it can fully prepare for the output in the coming year, and finally extend the useful life of the pistachio tree, so we should be careful when clearing the garden.

5. Auxiliary pollination

In order to improve the success rate of fruit setting, artificial pollination is a vital work. There are two main methods of artificial pollination. The first is artificial point pollination, which is time-consuming, but the fruit rate is extremely high. It is mainly to smear the pollen one by one, which is more troublesome, and those with less planting area can be considered. However, it is better to use the second method of dusting when planting in a large area, which is more efficient and has a good success rate. Finally, pollination is best done between 10: 00 in the morning and 4: 00 in the afternoon.
