The latest seed price and planting method of peach stone

Peach is a small deciduous tree of Rosaceae peach, native to China, with many cultivated varieties, widely cultivated all over the country, flowers can be ornamental, fruits can be eaten raw or preserved peaches, canned, etc., known as "Birthday Bun with Bean Paste Filling" and "Xiantao". Its nucleolus is also edible, let's take a look at the seed price and planting method of peach seed.

How much is the peach seed per jin?

The price of peach seed is about 10-15 yuan per jin, but it varies greatly due to seed quality, variety, market, season and so on. Peach trees are native to China and are widely cultivated in various parts of China. The more important varieties are nectarine, flat peach, Shouxing peach, green peach, etc., in which nectarine and flat peach are cultivated as fruit trees, and Shouxing peach and green peach are mainly used for ornamental purposes. Grafting propagation is the main method in production, and sowing, cutting and striping propagation can also be used to sow and propagate 25,30kg per mu.

Sowing methods of peach trees

After the peach is ripe, harvest the fruit, pile up and mash it, remove the pulp, dry and collect pure seedling seeds for autumn sowing, and soak the seeds for 5-7 days before sowing. The autumn seeder sprouted early in the following year, the emergence rate was high, and the growth was rapid and strong. When sowing in the next spring, the seedling seeds should be stored in wet sand for more than 120 days, with strip sowing, 10 cm strip, 1 cm deep, 6 cm soil cover after sowing, 3 cm high seedlings and fixed seedlings, with a distance of 20 cm to 25 cm.

Planting methods of peach trees

1. Garden selection: peach trees do not have strict requirements on soil, but it is appropriate to choose sandy loam with good drainage and loose soil, and the south slope is the best, but continuous cropping is avoided, that is, peach trees can no longer be planted on the land where peach trees have been planted.

2. Deep ploughing and soil improvement: peach trees must be deeply turned into terraces and thickened soil layers before planting, and then planting holes or ditches should be dug according to plant spacing, and flat dam and clayey soil should also be improved.

3. Planting time: peach trees can be planted in spring and autumn, but autumn planting is the best, autumn planting temperature is high, Rain Water is more, easy to recover after root damage, squatting time can be reduced in the coming year, sprouting is neat, 10 ~ 12 months planting is more appropriate.

4. Planting density: the planting density of peach trees should be determined according to variety characteristics, topography, soil conditions, shaping methods and cultivation methods. Generally, the row spacing is 3 × 4 meters or 3 × 3 meters, and 56 or 74 trees are planted per mu.

5. planting method: before planting, the peach tree will prune the injured root and the oversized main root, then straighten the plant, stretch the root system, cover the soil 5cm to 10cm, use your feet, and then irrigate through the water. After underwater infiltration, cover a layer of fine soil, or cover another layer of grass.

Disease and pest control of peach trees

1. Peach leaf shrink disease

[hazard characteristics] the leaf shrinking disease of peach is mainly harmful to leaves, twigs and young fruits.

[control methods] when the peach buds were swollen but not blooming in spring, ① was sprayed with Baume 5 degree stone sulfur mixture or 1 type Bordeaux solution. After diseased leaves were found by ②, the ascomycetes were removed and burned in time before forming the ascomycetes.

2. Peach scab

[hazard characteristics] peach scab is mainly harmful to fruits, but also to shoots and leaves. During the initial disease of the fruit, dark green round spots appeared on the fruit surface, and then gradually expanded.

[control methods] before germination, ① sprayed Baomei 5 stone sulfur mixture to eradicate or reduce the source of overwintering bacteria on branches, and sprayed Baume 0.2-0.4 stone sulfur mixture every other month from half a month to June. ② in winter combined with pruning, removal of diseased branches, or elimination to reduce the source of overwintering disease.

3. Peach anthracnose

[hazard characteristics] the young fruit showed dark brown, stagnant development, atrophy and sclerosis. When the larger fruit is infected, dark green water stains appear on the initial fruit surface, and the enlarged depression is dark brown.

[control methods] ① in winter combined with pruning to remove diseased branches and fruits and reduce the source of disease. ② was sprayed with Baume 5 °stone sulfur mixture before germination, or 1000 times of organic sulfur preparation or 70% methyl topiramate wettable powder since the fruit was large.

4. Peach tree rot

[hazard characteristics] Peach tree rot mainly harms the trunk and big branches, causing dead trees. When the disease is serious, the whole body is covered with glue, the bark tissue is rotten, the moisture has the smell of wine lees, and then it dries and shrinks, and there are black spots on it.

[control methods] ① cultivates tree potential and strengthens fertilizer and water management. ② scrapes the disease spot in time to the xylem, and then smears it with 40% fumaric arsenic or 50% bacilli. ③ burns the diseased and withered branches sawed every year in time and cannot be stacked near the orchard.

5. Peach gum disease

[harm characteristics] Peach gummy disease is an important disease of branches. In spring and summer, lenticels are the center of the new shoots, and some protuberant disease spots of different sizes produce colorless and translucent soft gum. In serious cases, the bark is cracked, the branches die and the tree is weak.

[control methods] ① should strengthen soil improvement, increase the application of organic fertilizer and protect the branches. The glue-flowing part of the ② tree is scraped off first, then smeared with 5 Baumetolite-sulfur mixture or quicklime powder, and then brushed with 70% methyl thiophanate or 50% carbendazim 20-fold solution after 1-2 days.
