Spinach planting methods: choose varieties, select planting sites, seed germination, sowing.

A, choose varieties

Planting spinach, if planted in the fall, you can choose wrinkled leaves, half-wrinkled leaf varieties, want to make its growth fast, you can plant the smooth leaf varieties, smooth leaves, if the growth of the upright, the color of the leaves should be light, it can be very fast growth.

If you are planting in summer, choose varieties with good heat resistance. Spinach seeds should also be selected to be full and free from insect eyes, and damaged seeds should be removed. Seeds should not be used if they have expired.

Second, choose the planting site

Planting spinach, you should choose the soil is more fertile, rich in organic matter of acidic soil, before you start planting to be ploughed, ploughed in the depth of 25cm or so, but also according to the fertility of the soil fertilization, an acre of land to impose 3,000kg of organic fertilizers, but also with the 25kg of ammonium sulfate and 15kg of potassium sulfate.

Three, seed germination

Before the start of sowing, the seeds should be soaked in water for at least 12 hours, and then kept at 4 ℃ for a day, and then placed in 20-25 ℃ environment germination, waiting for the seeds to sprout can be sown. Generally, seeds need to be treated if sown in summer and fall, and no treatment is needed for spring and winter planting, which are usually planted directly.

Four, sowing

When sowing, plant the seeds into a 1.3cm deep planting pit, and ensure that there is a spacing of 5cm between the seeds, and a row spacing of about 20cm. After sowing, cover the seeds with soil, pat the soil, and then water the soil to moisten it, and it will sprout in a week's time. If the seeds are sown in summer, it is necessary to build a shade net after sowing, otherwise too much sunlight will hinder the growth and development of the seeds.

Propagation

Must strictly select the female and male plants with the typical traits of this variety with good productivity. Selection can be carried out in three times: the first nutritive growth period, all the plants that do not meet the standard to pull out, the second in the absolute stamens moss but not pollen period.

Based on the height of the plant, the size of the spread and the shape of the leaves, select the plants that are growing vigorously, large leaves, and a long period of nutritive growth, and remove all the rest of the plants (including the absolute male plants). The third time in the pistil before flowering, in addition to maintaining part of the male and female plants or hermaphrodite plants, the rest of the male plants, poor plants all removed.

When the seeds of the selected female plants change color and the stems and leaves turn yellow, they can be harvested and mixed. Identify and compare the characteristics of the progeny of the original seeds and select them by another population mix to improve the seediness. Further characterize the typicality, productivity and consistency of their seeds, and propagate a large number of original seeds for next year's original seed production fields and production seeds.
