Embodiment 1
[0024] The seedlings were raised in the Xuan arc bamboo and wood type ordinary solar greenhouse on the semi-arid sandy soil at an altitude of 1920m. The organic matter content of the soil is 20%, the pH is 7.6, and the previous crop is the original seed potato. 20 days before seedling raising, deep plow 25-30 cm, apply 4500 kg of decomposed cow and sheep manure mixed with organic fertilizer per mu, and water with 20 tons of water per mu. The soil was shallowly turned 5 days before the seedlings were raised, and 20 kg / mu of diammonium phosphate and 5 kg / mu of potassium sulfate were applied together. Simultaneously apply 50% zinc sulfur phosphorus 0.3g / m 2 Insecticide, rake flat to make furrow, furrow surface width 120cm, furrow spacing 30cm, furrow height 20cm. Before sowing, put the dry seeds into nylon bags with fine sand and rub them until more than 90% of the seed coats have obvious scratches, and then soak the seeds in warm water at 50°C for 4-5 hours to make the water-a...
Embodiment 2
[0028] The seedlings were raised in the Xuan arc bamboo and wood type ordinary solar greenhouse on semi-arid sandy soil at an altitude of 2250m. The organic matter content of the soil is 15%, the pH is 8.0, and the previous crop is the original seed potato. 20 days before seedling raising, deep plow 25-30 cm, apply 4600 kg of decomposed pig manure organic fertilizer per mu along with the land preparation, and water with 20 tons of water per mu. The soil was shallowly turned 5 days before the seedlings were raised, and 20 kg / mu of diammonium phosphate and 5 kg / mu of potassium sulfate were applied together. Simultaneously apply 50% zinc sulfur phosphorus 0.3g / m 2 Insecticide, rake flat to make furrow, furrow surface width 120cm, furrow spacing 30cm, furrow height 20cm. Before sowing, put the dry seeds into nylon bags with fine sand and rub them until more than 90% of the seed coats have obvious scratches, and then soak the seeds in warm water at 50°C for 4-5 hours to make the ...
Embodiment 3
[0032]The seedlings were raised in the Xuan arc bamboo and wood type ordinary solar greenhouse on the semi-arid sandy soil land at an altitude of 1280m. The soil organic matter content is 12%, the pH is 7.8, and the previous crop is cabbage. 20 days before seedling raising, deep plow 25-30 cm, apply 5000 kg of decomposed pig manure organic fertilizer per mu along with land preparation, and water with 20 tons of water per mu. The soil was shallowly turned 5 days before the seedlings were raised, and 25 kg / mu of diammonium phosphate and 5 kg / mu of potassium sulfate were applied together. Simultaneously apply 50% zinc sulfur phosphorus 0.3g / m 2 Insecticide, rake flat to make furrow, furrow surface width 120cm, furrow spacing 30cm, furrow height 20cm. Before sowing, put dry seeds into nylon bags with fine sand and rub them until more than 90% of the seed coats have obvious scratches, and then soak the seeds in warm water at 50°C for 4-5 hours to make the water-absorbing swelling...
