The stems, leaves and roots of spinach are all edible, and some people refer to spinach as ? red-beaked green parrot? Spinach can be planted in the spring and autumn, usually autumn sowing, mainly in early August to early September to sow, planting spinach need to germinate, watering diligently, more fertilizer, the following I will share the fall spinach planting techniques.

A varieties of choice

Autumn spinach after sowing, the pre-temperature will be a little higher, to the late temperatures, light is still relatively abundant, very suitable for the growth of spinach, the varieties of requirements, although not very strict, but still to choose the heat-resistant disease-resistant, not easy to shoot up, fast-growing, precocious varieties.

Two, land preparation and fertilization

To choose a more sunny place, the requirements of the soil is loose and fertile, water retention and fertilization, drainage and irrigation conditions should be good, neutral acidic soil,. Note that after the harvest of the previous crop should be turned 20 to 25 centimeters deep, the residual roots are removed, the soil should be fully baked over white. In the preparation of the land, it is recommended that each acre of land should be put into the rotted organic fertilizer in 4000 to 5000 kilograms, calcium superphosphate is 25 to 30 kilograms, lime is 100 kilograms. The soil is leveled and harrowed, and made into flat beds or raised beds.

Three, sowing seedlings

Spinach sowing way: generally are used in direct broadcasting, and is mainly sowing, early fall spinach, it is recommended that it is best to retain the top film and cover the shade netting of the shed to planting, but also can be planted in the melons of the shed under the frame.

Spinach should be germinated and sown: because novice seeds are dormant, it is recommended that the best use of old seeds, this time of year can be sown dry seeds or wet seeds. In the early fall sowing due to still hot weather, this time it is more difficult to seedling, you can use germination wet sowing. The specific method is: put the seed in the sack, choose to dip in the evening, to the next morning and then take out, and then spread the seed, placed in the house in the shade, (previously in the bomb shelter), above and covered with wet sack, pay attention to the morning and evening of each day, but also with cool water once, to ensure that the seed of the wet, there are 7 to 9 days or so can be germinated and then start sowing.

Another method is to put the seeds in the refrigerator at a low temperature of about 4 degrees Celsius in the freezer, for treatment for 24 hours, after the end of the 20 to 25 degrees Celsius under the conditions of the germination of this method after 3 to 5 days can be sprouted and then sown.

Before sowing the seeds should be watered first, and then sown, pay attention to the topsoil can be lightly combed, so that the spinach seeds fall into the soil cracks inside, and then pour a layer of rotting human and animal fecal residue, or covered with 2 centimeters thick of fine soil. After that, cover with straw or shade netting, and remove the top part of the mulch in time when the spinach seedlings come out of the ground. At the same time in the seedlings have 1.5 ~ 2 leaves when to pull too dense seedlings, combined with interplanting to pull out weeds.

Four, autumn spinach field management

1, pay attention to shade

Seeking spinach seedlings is in the high temperature period, midday time to cover the shade net, in the showers and rainstorms before the advent of the shade net and cover the film, to prevent scouring, reduce humidity. In the heavy rain and then uncovered net uncovered film.

2, timely watering

Spinach seedlings due to the high temperature and rainy season, when the soil humidity is relatively low, so be diligent in watering, watering small, but also must be cool water, in the morning and evening each time. At the same time with the gradual growth of seedlings to gradually reduce the number of watering, in principle, is to keep the soil moist, do not use large water irrigation, pay attention to flooding after rain.

Autumn spinach planting, there will certainly be continuous rainfall and then suddenly clear the hot weather, in order to prevent spinach physiological water loss phenomenon occurs, to avoid causing the death of the rolled leaves, should be taken in the morning and evening watering method to cool down, in the seedling has 4 to 5 leaves, entered the exuberant growth period, this time the water demand is relatively large,, according to the moisture of the soil in a timely manner of watering, generally speaking, before harvest to irrigate 3 to 4 times. In general, before harvesting, you need to irrigate 3 to 4 times.

3, fertilizer management

To the autumn spinach fertilizer to early, light, hard, but also must be the soil surface dry when fertilizer, pay attention to the first light after the thick Shi. Also note that rainy days, including showers or heavy rain, or high temperature and high humidity south wind weather is not suitable for fertilizer.

Pay attention to fertilizer, due to the high temperature and dry weather in the early stage, after the growth of true leaves suitable for splashing 0.3% urea water, to the cooler weather, in the evening to watering splash a 20% or so of the lighter manure, in the subsequent growth process according to the growth of spinach plants and the lowering of the temperature, to gradually increase the concentration of fertilizer, pay attention to the first 15 days of the harvest to be Stop applying manure 15 days before harvest. In the spinach growth period, it is recommended to apply fast-acting fertilizers 2 to 3 times in stages, 10 to 15 kilograms of urea per acre, or 20 to 25 kilograms of ammonium sulfate.

4, timely harvest

Generally 35 to 40 days after sowing, seedling height of 10 cm, and there are 8 to 9 leaves, it began to batch to pull between the seedlings, pay attention to the spinach first soon to shoots of the harvesting point, while in the first plucking to fertilizer after the first time, the second time on the clear garden all the harvesting.

The above is the technical points of fall planting spinach, I hope to be able to help you spinach planting, such as you have any questions in the spinach planting process, you can also leave a message in the comments section, we *** with the discussion.
