The same spinach plants have different harvests.

Spinach is a cold-tolerant vegetable and a long-sunshine plant. Northern China also has winter sowing and spring harvest, commonly known as buried spinach. Let's learn about the cultivation methods of spinach, as follows:

First, spinach in sowing time is a kind of cold-tolerant and cool vegetable, which is beneficial to the growth of leaf clusters in the short-day cool season. Most of the cultivation in the arch shed around Shouguang in our province is sown around October 1.

Second, sowing generally does not need to raise seedlings, the use of direct seeding. Mainly by video broadcast or on demand. Before sowing, the seeds should be crushed and the fruits are dispersed. Under the condition of high temperature, the seeds germinate slowly. Therefore, the early sowing seeds need to soak and accelerate germination. After soaking in clean water for 12 hours, put them in the refrigerator freezer or well 20-30 cm above the water surface to promote germination. About 80% of the seeds can be sown after germination.

Large area planting is not suitable to choose this kind of budding method, now Shouguang, Qingzhou and other places mostly use planters to sow dry seeds.

Third, fertilizer and water management soil preparation at present foot base fertilizer, per mu of rotten organic fertilizer 2000-2500 kg, fully mixed, so that the soil has a good performance of water and fertilizer conservation. Topdressing is mainly water and fertilizer, diligent application, thin application, mixed application of human feces and urine, biogas liquid or compound fertilizer, harvest in different batches in the field, and topdressing in time after each harvest.

Fourth, pick bundles with roots: this kind of harvesting method mainly selects three or six handfuls or four or six handfuls, that is, 18 or 24 plants per hand. the market we are facing is generally the vegetable wholesale market in various cities or for supermarkets.

Leaf harvesting: the specific harvest requirement is to harvest only leaves with 5 cm stalks. This kind of harvesting method is mainly aimed at the processing market. Vegetable farmers can harvest according to the regulations of the processing plant, and the price is often 0.20-0.50 yuan higher than that of bundles.

Root removal of the whole plant: the specific requirement of this kind of harvest is to harvest the whole plant, remove the root, the smaller the root, the better, to not scatter the tree, and then pack it separately.

The above harvest methods are determined according to different market requirements, no matter which kind of harvest faces which market, the quality requirements of spinach are basically the same (the requirements are leaf thickness, leaf color black, stem solid, etc.).

Spinach planted through the same method introduced above and then the use of three harvest methods, but also have different harvest results, you can have a try.
