When is the right time to plant vegetable hearts? How to manage to high yield?

Different varieties of cabbage, suitable for cultivation in different seasons, the cultivation conditions required are also different. Vegetable shoots, also known as cabbage shoots, green cabbage shoots, planting does not need to be germinated, to be diligent fertilizer, diligent picking. Here we take a look at the planting time and high-yield management techniques.

A, suitable for vegetable heart planting time

Generally can be cultivated in the spring and fall, if the family planting more choice in the fall, North China is in August to September for sowing, the Yangtze River Basin and the southern region in September to October sowing, the southern region is planted all year round. Two months after sowing can be harvested.

Because of the different varieties of cabbage heart, then the suitable cultivation season will be different. If in the Yangtze River basin and the south of the region, early-maturing varieties of beetroot can be sown in April to August, 30 to 45 days after sowing can begin to harvest, May to October is the supply of beetroot. Medium-maturing varieties of choy sum are sown from September to October, 40 to 50 days after sowing. They are marketed and supplied from October to January of the following year. Late-maturing varieties are sown from November to March, harvested 45 to 65 days after sowing, and supplied to the market from December to April.

The northern region can be divided into two ways of cultivation in the open field and protected cultivation, in the open field cultivation can be divided into spring, fall two seasons of open field cultivation, is the use of early and late maturing varieties of sowing in March to April, in late April to early June harvest. Fall open field cultivation is to use early and medium maturing varieties, sown in August to September, harvested in September to November. In the case of protected cultivation, late-maturing varieties are utilized, sown from October to February, and harvested 2 months after sowing.?

Two, cabbage planting high-yield management techniques

1, mastered cabbage live seedling technology

Early, medium-maturity varieties of cabbage because of the growth period is relatively short, generally suitable for direct broadcasting-based. But live also has the disadvantage of occupying too long, can be replanted index is relatively low, at the same time there will be vegetable shoots of color is too light, and is the size of the uneven, petiole is also longer, and easy to hollow, resulting in the draw of shoots is not consistent.

Winter and spring season seeding should be prevented from low temperatures, especially cold waves and low temperatures, to avoid the emergence of ? Cold buds? and lead to the early development of the vegetable heart plant, causing a decline in the yield of the vegetable heart. Keep track of the weather to sow seeds, and avoid sowing in summer and fall when there are storms to prevent being washed away by heavy rain. After sowing, cover the beds with shade netting or straw, and drench them with enough germination water. Mulching is used for heat preservation and protection from rain and sun in the summer and fall, and for heat preservation and protection from cold in the winter and spring. Be careful to remove the mulch in time after the emergence of seedlings to prevent the seedlings from growing.

The amount of seed sown should be chosen according to the season. In the spring and summer, due to the unsuitable climatic conditions, so the amount of seed should be increased appropriately, generally recommended that each mu of land sowing is 0.4 to 0.5 kg, in the fall and winter season climate is suitable, the amount of seed should be reduced appropriately, it is recommended that the amount of seed sown per mu of land is 0.3 to 0.4 kg.

2, grasp the good vegetable heart seedling technology

Because of the late ripening of the growing period of vegetable heart is relatively long, can be used in the open ground or seedling tray seedling. The use of seedling transplantation can shorten the time of occupation of the field, in order to improve the land utilization rate to increase the number of replanting. Seedling transplanted plants it draws shoots neatly, cabbage shoots size is neat and uniform, and is the heart of the cabbage color is better and not hollow, the heart of the cabbage petiole short heart of good quality, must pay attention to the time of transplanting.

You can also use a greenhouse or a simple shed for seedlings, winter and spring season cultivation can also be used to protect the cold protected nursery, to be maintained at the right temperature conditions to promote the healthy growth of seedlings.

The use of seedling tray seedling, pay attention to before sowing with good nutrient soil. Pay attention to the prevention of pests and diseases during the seedling period.

3, mastering the vegetable heart seedling technology

Generally the early varieties of the growth period is relatively short, the plant is also relatively small, can be appropriate for the dense planting, late varieties of the growth period is longer plant is also relatively large, can be appropriate for the sparse planting in the fall and winter seasons due to the climate is more suitable for the appropriate planting of some of the sparse, the spring and fall seasons. Rainy and high temperature, the growing period is also relatively short, can be appropriate to some dense. In the seedlings of the true leaves began to stretch when the timely removal of too dense seedlings and weak seedlings. Ensure the nutrient growth area of the seedlings. Prevent the seedling from growing and reducing the quality of the seedlings. When the seedlings have 3 leaves can be combined with replanting to carry out the second inter-seedling and seedling, pay attention to the selection of healthy seedlings to replanting, and to maintain the appropriate spacing of seedlings.

If you use hole tray seedling in the seedling grows 1 true leaf when you have to inter-seedling, each hole to leave 1 strong seedling.

4, mastering the fertilization technology

Because the vegetable is fast-growing vegetables, growth is very fast, the growth period is relatively short, the growth is very large, coupled with the root system of the vegetable is relatively shallow, and the ability to absorb the poor, planting is more dense, so for the fertilizer requirements is very strict, the fertilizer and plant growth is basically a positive correlation, so it is necessary to strengthen the fertilization. Positive correlation, so it is necessary to strengthen the management of fertilizer to be able to obtain the high quality and high yield of vegetable heart.

Must apply enough fertilizer, in the growth period to timely fertilizer, in the summer and autumn cultivation of vegetable heart, high temperature and rain is not conducive to the growth of fertilizer during the growth period, pay attention to the application of fertilizer to the base fertilizer, to the base fertilizer. Fertilizer must master the diligent application, early application, and thin application of choice, pay attention to the pre-light, in the middle and late to heavy, in general, to fast-acting nitrogen fertilizer is the main, but also appropriate application of phosphorus and potash fertilizer, in order to improve the yield and quality of the vegetable heart.

The above is the planting time of vegetable heart and some high-yield management technology points, I hope it can help your vegetable heart planting.
