Do you need germination to grow overwintering spinach? How to improve the emergence rate?

Of course, germination is needed, and if you want to improve the emergence rate, you must use some chemical fertilizers to provide enough nutrients, and have sufficient sunlight and sufficient water.

Of course, the best thing to do is to increase the temperature in the nursery room, so that the emergence rate can be increased.

There is no need to promote germination, and if you want to improve the emergence rate, you need to select good seeds.

Plant autumn spinach, master these 3 seedling preservation skills, spinach safe wintering, bumper harvest!

The suitable sowing period is between the beginning of autumn and the "white dew", that is, from August 25 to September 5. Sowing too early, the overwintering seedlings grow large, the outer leaves are senescent, and the cold resistance is weak; Sow too late, overwintering seedlings.

Small, the second spring quickly moss, at the same time the seedlings are not cold-tolerant, not resistant to wind and drought, and are very easy to dry up and die.

Spinach planted in August and autumn, exploration of spinach seed retention method and detailed explanation of germination method.

To plant spinach, first put the seeds at temperature.

Soak in water for four or five days, wait until the seeds are swollen and full of openings, roll them into the moist, fertile soil of the canopy, and then rake the ground again with a rake, so that the seeds roll into the cracks of the soil, and soon they will take root and sprout.

Overwintering spinach is usually sown between mid-October and early November.

1. The planting time of spring spinach.

After the beginning of spring, when the temperature rises to more than 5 ° C, you can start sowing, March is the appropriate period for sowing, 30-50 days after sowing to harvest, varieties should choose late sprouting, late round leaf pine, spring and autumn large leaves, Shenyang round leaves, Liaoning round leaves, etc.

2. The planting time of summer spinach.

Summer spinach is often sown in stages from May to July, and harvested from late June to mid-September.

3. The planting time of autumn spinach.

Autumn spinach is sown in August and September, and can be harvested in batches 30-50 days after sowing. Varieties should be selected from early-maturing varieties that are more heat-tolerant and fast-growing, such as plowshare pine, Chinese pineapple No. 1, Guangdong round leaves, spring and autumn large leaves, etc.

4. The planting time of overwintering spinach.

Overwintering spinach is usually sown in mid-October - early November, harvested in batches around the Spring Festival, it is advisable to choose medium and late-maturing varieties with strong winter, late sprouting and strong cold tolerance, such as round-leaved pineapple, late-round-leaf pineapple, Chinese pineapple No. 1, Liaoning round-leaved pineapple, etc.

Sowing method: choose loose and fertile, water and fertilizer retention, good drainage and irrigation conditions, slightly acidic loam is better, and pH value. 4000 kg of rotting organic fertilizer per mu is applied to the mu of land preparation, 40 kg of superphosphate, leveling and fine, winter and spring should be done high furrow, summer and autumn should be done flat furrow, furrow width meter.

Spreading is generally used. Summer and autumn sowing is to soak the seeds in water for 12 hours one week before sowing, put them in a well or in a refrigerator or refrigerator or refrigerator around 4 oC for 24 hours, and then germinate under the condition of 20-25 oC, and sow seeds after germination in 3-5 days. Dry or wet seeds can be sown in winter and spring.

Cultivation techniques

Prepare the land for furrowing. Choose loose and fertile, water and fertilizer retention, good drainage and irrigation conditions, slightly acidic loam with good pH value. 4000 kg of decomposed organic fertilizer per mu of land preparation, 40 kg of superphosphate, leveling fine, winter and spring should be done high furrow, summer and autumn should be done flat furrow, furrow width meter.

Sowing seeds and raising seedlings. Spinach plots are generally sown. Summer and autumn sowing is to soak the seeds in water for 12 hours one week before sowing, put them in a well or in a refrigerator or refrigerator at about 4 °C for 24 hours, and then promote germination at 20-25 °C, and sow seeds after 3-5 days of germination. Dry or wet seeds can be sown in winter and spring.

Kilograms of sowing per mu.

After pouring the bottom water on the furrow surface, sow the seeds, lightly rake the topsoil with a tooth rake, so that the seeds are sown into the soil, and cover the furrow surface with a layer of plant ash. If the temperature of winter sowing is low, the furrow should be covered with plastic film or shade net to promote the emergence of seedlings, and the seedlings should be removed after emergence.

Field management. The soil remains moist after winter spinach planting. When there are 3-4 true leaves, properly control the water to facilitate overwintering. When there are 2-3 true leaves, the seedling spacing is 3-4 cm.

According to the seedling condition and weather, water and fertilizer were applied top-notch, and the feces and urine of ripe people were mainly decomposed. Frost and ice and snow weather should be covered with plastic film and shade nets for insulation, which can be covered with small arches. After the beginning of spring, choose a sunny day to apply well-rotted light manure water to prevent early sprouting.

Pest control

Aphids are sprayed with 40% dimethoate 1000 times solution, or 50% anti-aphid 2000-3000 times solution.

Leaf miner flies are sprayed with 1000 times of 50% phoxanthion EC or 1000 times of 80% trichlorfon powder.

Downy mildew was sprayed with 58% Radomir 500 times, or 75% chlorothalonil 600 times.

Anthrax is sprayed with 50% methyl tobuzine 500 times, or 50% carbendazim 700 times.

The overwintering spinach planting time and method are as follows:

1. Sowing time.

1) Timely sowing is a key factor for the success of overwintering spinach planting, and it can be sown when the average daily temperature drops to 17-19°C according to the climatic conditions of various places.

2) The sowing time is generally from mid-October to early November, and the spinach can be harvested when the plant height reaches more than 10cm.

2. Organize the land.

1) After the harvest of the previous crop, be sure to clean the soil immediately after the crop residues and stones, and then apply sufficient base fertilizer.

2) Generally, 4500 kg of decomposed organic fertilizer and 25-30 kg of superphosphate can be applied per mu, and then ploughed with a plough after fertilization, with a depth of 25cm, and the loose soil is conducive to spinach rooting.

3. Seed selection and sowing.

1) You can choose spinach seeds with strong cold tolerance, full grains, and no diseases and pests, soak them in water for 24 hours, and then place them in an environment of 25 °C to promote germination, which can improve the germination rate.

2) Dig a planting ditch in the field, and then use the method of spreading to sow evenly, and cover the soil and plastic film after sowing, so that the suitable temperature can be maintained.

4. Field management.

1) After wintering spinach planting, when the seedlings grow to 3-4 true leaves, be sure to control the watering, which is conducive to the overwintering of the plants, and generally sprinkle water once a week.

2) In frost and ice and snow weather, we must pay attention to the insulation of plastic arch shed, and you can choose to apply rotted thin manure water on sunny days after spring, which can prevent spinach from sprouting early.

Overwintering spinach is generally planted in mid-October and early November, at this time not only grows luxuriantly, but also the best period for spinach vegetative growth.

For the wintering spinach when will be planted with high quality, generally speaking, it is best to plant in mid-October and early November, due to the dry and cold weather in winter, there is frost in the morning and evening, which is conducive to the vegetative growth of spinach, and it is also the growth period of spinach, and the yield will be very large.

If you want to plant better spinach in winter, the first thing is to ensure the quality of seeds, generally choose varieties that are easy to smoke fast, strong wintering, cold tolerance, good quality, and fast growth, and are common in life, mainly spinach, pinehash No. 10, pinehash No. 9.

And if you plant spinach in winter, it is best to apply foot fertilizer in the soil to prepare the land finely, if you sow late, it is best to soak the seeds in cold water for about 12 hours, and then dry the seeds for 3 days.

1. Spring planting

Planting spinach in spring is generally the best when the temperature rises to more than 5 degrees after spring, and it is sown in March in spring, and it is harvested in about April and May.

2. Summer planting

Summer planting is generally in May and July to begin to sow in stages, in mid-June to mid-September harvest, summer high temperature pay attention to cooling and moisturizing, strengthen fertilizer and water management, and irregular soil turning once, generally can choose plowshare pine, Chinese pine No. 1, Guangdong round leaves, etc.

3. Autumn pine

The yield of spinach planted in autumn will also be very large, generally in the autumn of August and September to start sowing, to September and October in batches, and in the autumn planting is best to disinfect the seeds, and then put them in a low temperature refrigerator or cold water for 24 hours of treatment.
