Generally, it will not be frozen under the low temperature of - 3 ℃, so it is only necessary to build a large arch shed when planting in Northeast China(square grow pots). Canola in big arch shed is not strict on harvesting period. It can be harvested and listed at any time according to the market demand(bulk 1.5 gallon pots). If it wants to be listed in winter, it can obtain greater economic benefits. Sowing time can be chosen in the mid October of the solar calendar.


In the north of China, direct seeding is adopted in the big arch shed(cheap plastic plant pots bulk). Rape seeds in the north are usually packaged commercial seeds. Generally, the amount of seeds used per mu can be quantified according to the local soil moisture and soil conditions, with an average of 300 grams of seeds per mu(2 gallon plant pots distributor). When sowing, a certain proportion of soil should be mixed in the seeds, and the seed amount of one mu of land should be mixed with about 1500 grams of soil.


Select the land with deep soil layer, good texture, high soil fertility, low salt content and good drainage and irrigation conditions(sureroot plug trays bulk). Generally, rape is a crop with strong cold resistance, and its seedlings are also relatively cold resistant. Rape can be divided into two sowing methods: seedling raising and direct seeding(bulk 2 gallon containers). When the relative humidity of soil is lower than 70%, the lower leaves turn red, the whole plant is dark green and lusterless, or the leaves wilt at noon, irrigation should be done immediately.


After sowing, pay attention to heat preservation(large plastic terracotta pots). After sowing, the temperature shall be kept at 20-25 ℃ in the daytime and about 15 ℃ at night. About 7 days after sowing, the seedlings will break through the soil and enter the seedling stage of rape. After the seedlings come out, they need to be carefully managed(3 gallon nursery container wholesale price). Temperature from emergence to pre planting: after emergence, the temperature is kept at 15-20 ℃ in daytime and about 10 ℃ at night.


The early seedling is required in the seedling stage of rape(plastic plant pots wholesale suppliers). The principle to be mastered is to keep dense and sparse, to remove weak and keep strong, and to keep even. Generally, the seedlings are divided into two times, the first time when the first true leaf appears after the seedling is full, the leaves are not overlapped from the middle to the leaves(24 cell trays bulk). The second thinning was carried out when the second true leaf appeared, and the seedling was fixed at the third leaf stage.


After sowing, cover the seeds with a rake under 1 to 2 cm of the soil, and then water them once(plastic plant trays wholesale). When there is a strong wind cooling weather in the northern region, the general practice is to build a small arch shed or cover a layer of plastic film in the arch shed, so as to form the heat preservation measures of the shed in the shed, so that the temperature in the shed can rise 5 to 8 degrees Celsius(4 cell trays bulk), generally ensuring the normal growth temperature of the seedlings.
